DESCRIPTION
\layout Standard
-lmc can be invoked to generate configuration data associated with systems
- in a Lustre cluster.
+At present
+\series bold
+\emph on
+lmc
+\series default
+\emph default
+, when invoked, adds configuration data to the config file.
+ In future,
+\series bold
+\emph on
+lmc
+\series default
+\emph default
+ will also be able to remove configuration data or convert its format.
+ A Lustre cluster consists of several components - MDS's, mount-points,
+ OSTs, LOVs and whatever those reference (e.g nets and profiles).
+ A single configuration file would be generated for the complete cluster.
+ In the
+\series bold
+\emph on
+lmc
+\series default
+\emph default
+ command line interface, each of these components is associated with an
+
+\emph on
+objecttype
+\emph default
+.
+
+\layout Standard
+
+The
+\emph on
+objecttype
+\emph default
+ refers to a collection of related configuration entities and can be one
+ of
+\series bold

+We describe the arguments required for the addition of each
