+=head1 DESCRIPTION
+
+This command can be used in 3 modes: generate release manifest, create delta, and apply delta.
+
+Generate Release Manifest :
+Generates a release manifest file, which lists all files available in the reference baseline at the receiving archive. It is used in create delta mode, in order that it has an accurate representation of the reference baseline to make the delta against.
+
+The release manifest contains the list of components and their versions in the reference baseline environment. It also lists all the files in each component, and all the metadata files, and each file's size, timestamp and MD5 checksum.
+
+
+Create delta mode :
+Creates a smallest possible delta package, using which whole baseline can be reconstructed at the receiving site. this delta package contains deltas for modified files from reference version to the nominated version of a component, newly added files for the existing components, newly added components for the baseline and delta release manifest file. This delta package can be transferred by the user to receiving site instead of whole baseline.
+
+
+Apply delta mode :
+Reconstructs a nominated baseline using reference version and delta release package which is created in create delta mode. Using create delta and apply delta mode, amount of data to be transferred from sending site to receiving site can be reduced.
