To use rcs2ws:
Type rcs2ws -p [parent_dir] -n [files | directory] at the prompt.
The -p option is required to name the RCS source hierarch.
The -n option allows you to see what would be done without actually doing anything.
Relative file names are interpreted as being relative to parent_dir.
The CODEMGR_WS environment variable contains the name of a user's default workspace. This workspace is automatically used if the -w option is not specified. If you wish to designate the child workspace, use the -w option. See man rcs2ws(1).
If the current directory is contained within a workspace, the containing workspace is used as the child workspace. If workspace does not exist, rcs2ws creates it.
Use the "." directory to specify that every RCS file under parent_dir should be converted.
When all is as you wish, go on to Step 2.
