+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+not price. Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+\f
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+\f
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+\f
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+\f
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+\f
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+\f
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+\f
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+\f
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>

+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your

+to be enabled. This is set by default; Use "no" to disable.
+
+Option --with-automount=<automount-file-name> will cause automount support
+to be included. If <automount-file-name> is not supplied, a default value
+of ".mount" will be used, matching the Lustre documentation.
+
+To build:
+
+Just `make' it.
+
+Automounts
+----------
+
+For a full description of this see the "Lustre Book" at:
+ <http://www.lustre.org/docs/lustre.pdf>
+
+In short, though, whenever a component is being looked up in a directory and
+that directory has the "set-UID" bit set, then the directory is
+searched for a special file. By default, that file is called ".mount" but
+you may set it to any name using the --with-automount option described
+earlier.
+
+If the content of that file has something formatted, exactly:
+
+<file-system-type>:<source>
+
+Then the <source> description is mounted on the directory containing the
+special automount file and being used as the parent in the lookup. If the
+mount is successful, the parent is replaced with the newly mounted directory
+and processing continues. If the mount fails, or the automount file
+does not exist or cannot be read, everything continues as though the operation
+had never been attempted.
+
+File systems, or volumes, or file-sets, or whatever they are called, that
+have been automounted may also be automatically unmounted when resource
+is required. They are not on a timer, unless the file system driver implements
+one for them. They just disappear as resource is needed elsewhere. As they
+were automatically mounted to begin with, they should re-establish as needed,
+transparently.

+This "incore" file system driver is a self-contained file system. It does
+not use any resource external to the node.
+
+It is primarily intended for enabling an efficient compute-node bootstrap. It
+might also be useful for a very small scratch file system, holding device
+files, and the like.
+
+The root directory i-node is manufactured on the fly. The source specification
+for the mount() call should be something like:
+
+ <perms>+<uid>+<gid>
+
+Where:
+ <perms> are the directory permissions masked by 0777
+ Note -- no umask is applied.
+ <uid> should be the owner's uid
+ <gid> should be the owner's gid
+
+Most operations are supported, with the notable exception of symbolic
+links.
+
+In the implementation, the driver is really set up to export most
+useful symbols without polluting the name space or contending with
+other public symbols. However, the symbols are not yet exported. If
+we ever require a proc-fs style file system, this could be very useful
+provided a little extra work is done to allow other drivers to overload
+some operations. Particularly the file ops, I would think.

+To run the tests, just do a "make check" in the tests subdirectory.
+On the CPlant alpha systems, 3 of the 7 tests in test_all.pl are excluded
+due to known problems (problems as of the date of writing this; they
+may have since been fixed). You can also manually run the individual
+tests or ./test_all.pl. If you are running on CPlant, you need to
+run test_all.pl with a -alpha argument. Either "make check" or
+test_all.pl will run the 7 basic functionality tests (explained
+below) and report the total number of passes and failures.
+number of passes and failures.
+
+-----------------------SCRIPTS---------------------------------
+
+There are a total of 8 scripts: test_copy.pl, test_list.pl,
+test_getcwd.pl, test_stats.pl, test_stdfd.pl, test_path.pl,
+populator.pl, and verifier.pl. All but the last two scripts
+are ran with the test_all.pl script. Here is an explanation
+of the scripts. All scripts take an optional "-alpha" arg
+for running the scripts in an alpha/cplant environment. The
+alpha arg makes certain assumptions about the running of the
+environment; for example, it does not initilization and it
+starts off the test driver with yod.
+
+test_copy.pl <src> <dest> : This copies a file from src to dest.
+ : It runs a system cmp to verify that
+ : the two files are equivalent
+
+test_list.pl [-p] <dir> : This comes in two forms.
+test_list.pl [-p] <fstype:mdir> <dir> : In the first form, it will
+ : parse through the getdirentries
+ : result in order to generate a
+ : a listing. If the -p option is
+ : given, it will print out the
+ : listing. In the second form, it
+ : mounts mdir into dir and then does
+ : the listing
+
+test_getcwd.pl <dir> : Tests getcwd by verifying that setting the current
+ : working directory to dir and then calling getcwd
+ : returns dir
+
+test_stats.pl <file> : Verifies that the set of stat calls (stat, fstat,
+ : fstatvfs, statvfs) return the same set of stats for file
+ : and that the calls return the same items as Perl's stat
+ : call (which would use a native library and not libsysio)
+
+test_stdfd.pl <file> : Verified that stdin, stdout, and stderr can be opened and
+ : either written to or read from
+
+test_path.pl <path1> <path2> ... : Print each path listed and its type.
+ : If no paths are given, paths are read
+ : from stdin until a "quit" is given
+
+populator.pl [-seed seed] : Create a file and populate with random numbers.
+ [-file filename] : Will use the given seed for the random number
+ [-bytes bytes] : generator if it is given, otherwise it uses the
+ : the current time as a seed. The seed used is
+ : returned. If no filename is given, the file
+ : will be named randfile.seed.procnum, where seed
+ : is the seed used and procnum is the process number
+ : of the script. If no bytes are given, 1024 bytes
+ : are written. All write commands use libsysio
+
+
+verifier.pl <-seed seed> <-file fname> : Verifies that all bytes in the file fname
+ : (which was created with populator) match the
+ : random numbers which would have been used with
+ : the populator, using the given seed.
+
+
+
+-----------------------------TEST DRIVER---------------------------------
+
+
+There are 6 basic commands for the test driver, CALL, PRINT,
+ALLOC, FREE, HELP, and exit (EXIT, quit, or QUIT will also work).
+
+CALL is the main command for running libsysio calls. The format
+will depend on the particular libsysio command being ran.
+Basically, the format is CALL cmd args. The available commands
+used with CALL are (in no particular order):
+
+fstat iwrite read chdir
+fstatvfs iwritev readv chmod
+fsync list rmdir chown
+ftruncate lseek sizeof close
+getcwd lstat stat cmpstr
+getdirentries mkdir statvfs creat
+init mknod symlink debug
+ioctl mount truncate dup
+iodone open umask dup2
+iowait umount endian ipread
+printline unlink ipreadv pread
+write fcntl ipwrite preadv
+writev fdatasync ipwritev pwritev
+fill iread pwrite ireadv
+
+The specifics of the commands are explained later.
+
+The return value from a command can be saved and referenced later
+by using a syntax similar to $foo = x. Commands can be combined, such
+as:
+
+CALL fstat ( $fd = CALL open foo ) ( $buf = ALLOC 128 ),
+
+with some cautionary notes. First, everything needs to be
+seperated by a space. File names with spaces in them need to be quoted,
+as in:
+
+$fd = CALL open "file with spaces" O_RDONLY
+
+Second, any value that is used needs to be identified with an identifier.
+In other words, the command:
+
+$buf = ALLOC ( CALL sizeof stat )
+
+will not work, but the command
+
+$buf = ALLOC ( $size = CALL sizeof stat )
+
+will.
+
+
+All commands return a 4 digit status code. The codes are:
+
+0000 : Success. This does NOT necessarily mean that the libsysio
+ : command returned success, only that there were no errors
+ : in issuing the command to libsysio. To get the result of
+ : the libsysio command, use PRINT $$ . PRINT $errno will return
+ : the last error code.
+0x001 : Invalid arguments given to command
+0x002 : Invalid command issued
+0x004 : Invalid variable identifier given
+
+
+ALLOC takes a size argument and an optional alignment argument.
+FREE takes the variable to free as an argument.
+HELP without any arguments displays the list of commands.
+HELP <cmd> will give information on the specific command
+
+PRINT take several forms. To just print out a variable, type
+PRINT $var-name. If the variable is an integer, it will return
+the integer. If it is a string, it will print out the string.
+If it is a buffer, it will print out the buffer as a series of
+hex digits. Note for most buffers, the test driver will not
+know what it contains--just because it should contain a string
+does not mean that the driver will know that.
+
+The other form of PRINT is:
+
+PRINT $var_name <offset> <length> <type>
+
+which will print out length units of the given type starting at
+the given offset. The length is the total length in bytes, so
+for an integer, a length of 4 would only print out one integer.
+The length argument is ignored for strings. Allowable types are
+INT SHORT CHAR and LONG.
+
+For most of the CALL commands, their format is similar to the
+related sysio call. The ones that do not have a corresponding
+sysio call are listed below:
+
+init: This MUST be called prior to any sysio calls. It initilizes
+ : libsysio
+
+printline: If debugging is turned on, this will print a line number
+ : with any debug lines
+
+fill <val> <type> <size> <offset> <buf>: Fills buffer buf with size
+ : bytes of val starting at
+ : buf+offset. The type of val
+ : can be UINT. STR, or PTR and
+ : is given by the type arg
+
+list <dir>: Lists contents of dir. If no dir is given, uses cwd
+
+debug <num>: Sets debug level to num
+
+sizeof <obj>: Gives the size of the obj. Valid objs are char, int,
+ : long, flock, stat, and statvfs
+
+endian: returns 0 if the machine is little endian, one otherwise
+
+cmpstr <buf1> <buf2>: Issues a strcmp call on the two buffers to
+ : see if they are the same. Returns 0 for a
+ : match
