43: .Sh DESCRIPTION
44: The
45: .Nm
46: program acts as both client and server for the use of and administration of
47: a CVS source repository.
48: CVS is used to maintain version information on files that are kept in a
49: repository.
50: Although it is more commonly used to track changes in source code, there
51: are no real limitations to the type of files that you can store in a
52: repository.
53: .Pp
1.7 jfb 54: Unless the
55: .Fl f
56: option is specified,
57: .Nm
58: reads its startup configuration file
59: .Pa .cvsrc
60: from the home directory of the user who invoked it.
61: This file is used to specify implicit options passed to
62: .Nm
63: or one of its commands whenever it is invoked.
1.16 jmc 64: See
65: .Xr cvsrc 5
66: for further information.
1.7 jfb 67: .Pp
1.1 jfb 68: The following options are supported:
1.15 jmc 69: .Bl -tag -width "-e editorXX"
1.1 jfb 70: .It Fl d Ar root
71: Use
72: .Ar root
73: as the path to the root directory of the CVS repository.
74: The value must specify an absolute path.
75: .It Fl e Ar editor
76: Use the program
77: .Ar editor
78: whenever editing log information.
1.8 jmc 79: This option overrides the environment variables CVSEDITOR, VISUAL, and EDITOR.
1.1 jfb 80: .It Fl f
1.7 jfb 81: Do not read the user's configuration file on startup.
1.1 jfb 82: .It Fl l
83: Suppress logging of history information.
84: .It Fl Q
85: Be extra quiet.
86: Only error messages will be displayed.
87: .It Fl q
88: Be quiet about reporting.
1.20 jmc 89: .It Fl s Ar var Ns = Ns Ar val
90: Set the value of the internal variable
91: .Ar var
92: to the string
93: .Ar val .
1.15 jmc 94: .It Fl t
95: Trace program execution.
1.1 jfb 96: .It Fl v
97: Display version information and exit.
1.15 jmc 98: .It Fl z Ar level
99: Specify the compression level to
100: .Xr gzip 1
101: when transferring files.
102: The compression level ranges from 1 to 9,
103: with 1 being the fastest,
104: and 9 providing the best level of compression.
105: The default is 6.
1.1 jfb 106: .El
107: .Sh COMMANDS
1.3 jfb 108: The following commands are supported by

1.3 jfb 113: .Xc
1.7 jfb 114: .Pp
1.1 jfb 115: Before a file is known to CVS, it must be added to the repository using
116: this command.
117: Adding a file does not actually publish the contents of the
1.7 jfb 118: file, so you must
1.11 jmc 119: .Ic commit
1.7 jfb 120: the first revision in order to let other users see the file with the
1.11 jmc 121: .Ic update
1.4 jfb 122: or
1.11 jmc 123: .Ic checkout
1.4 jfb 124: commands.
1.1 jfb 125: .Pp
1.7 jfb 126: Although adding a file does not involve a log message, it is possible to
127: specify one to include with the action, using the
128: .Fl m
129: option.

1.23 xsa 148: For each line of any files specified, show information about its
149: last revision.
150: The information given is the last revision when a modification occurred,
151: the author's name, and the date of the revision.
1.26 xsa 152: .Pp
153: The
154: .Fl f
155: flag is used to force the use of the head revision if the specified
156: tag or date is not found.
157: This can be used in combination with
158: .Fl D
159: or
160: .Fl r
161: to ensure that there is some output from the
162: .Ic annotate
163: command, even if only to show Revision 1.1 of the file.
164: The
165: .Fl l
166: flag is used to limit the scope of the search to the local directory
167: only and to disable recursive behaviour, which can be requested with the
168: .Fl R
169: flag.
170: The
171: .Fl D
172: flag shows the annotations as of the latest revision no later than
173: .Ar date .
174: The
175: .Fl r
176: flag shows annotations as of revision
177: .Ar rev
178: (can be a revision number or a tag).

1.7 jfb 202: .Pp
1.1 jfb 203: The
1.11 jmc 204: .Ic commit
1.1 jfb 205: command is used to send local changes back to the server and update the
206: repository's information to reflect the changes.
1.27 xsa 207: .Pp
208: The
209: .Fl l
210: flag is used to limit the scope of the search to the local directory only.
211: Sometimes one might want to force a file to be committed, even though
212: it is unchanged: this can be done using the
213: .Fl f
214: flag, which also has the effect of disabling recursive behaviour,
215: which can be requested with the
216: .Fl R
217: flag.
218: When using the
219: .Fl n
220: flag, programs listed in the CVSROOT/modules file do not get executed.
221: The
222: .Fl m
223: flag can be used to specify a log message on the command line which
224: suppresses the editor invocation, or use the
225: .Fl F
226: flag to specify a
227: .Ar file
228: as argument which contains the log message.
229: The
230: .Fl r
231: flag can be used to commit to a particular symbolic or numerical revision.

1.5 jfb 246: program, except that the differential comparisons that it generates are

315: when the edition first started, the host from where the edition

1.2 jfb 793: .Sh CAVEATS
794: This CVS implementation does not fully conform to the GNU CVS version.
1.3 jfb 795: In some cases, this was done explicitly because GNU CVS has inconsistencies
1.2 jfb 796: or ambiguous behaviour.
1.3 jfb 797: Some things have also been left out or modified to enhance the overall
798: security of the system.
799: .Pp
800: Among other things, support for the pserver connection mechanism has been
801: dropped because of security issues with the authentication mechanism.
