1.21 jmc 44: The
1.1 xsa 45: .Nm
1.21 jmc 46: program is used to check out revisions from RCS files.
1.23 jmc 47: .Pp
48: When a file is checked out,
49: a copy is taken from the RCS repository,
50: minus its RCS information,
51: and placed in the current working directory.
52: Files may be checked out as the most recent revision
53: or according to a specific revision,
54: using the
55: .Fl r
56: option.
57: .Pp
58: Files are checked out in one of two possible modes:
59: unlocked (the default) or locked (using the
60: .Fl l
61: option).
62: In unlocked mode, any user may check out the file for reading.
63: If changes are to be made to a file though,
64: it will have to be locked using the
65: .Fl l
66: option.
67: During this time,
68: no other users may check out the file whilst it is locked.
1.25 jmc 69: .Pp
