12 'git cvsimport' [-o <branch-for-HEAD>] [-h] [-v] [-d <CVSROOT>]
13 [-A <author-conv-file>] [-p <options-for-cvsps>] [-P <file>]
14 [-C <git_repository>] [-z <fuzz>] [-i] [-k] [-u] [-s <subst>]

16 [-r <remote>] [<CVS_module>]
21 Imports a CVS repository into git. It will either create a new
22 repository, or incrementally import into an existing one.
24 Splitting the CVS log into patch sets is done by 'cvsps'.
25 At least version 2.1 is required.
27 You should *never* do any work of your own on the branches that are
28 created by 'git-cvsimport'. By default initial import will create and populate a
29 "master" branch from the CVS repository's main branch which you're free
30 to work with; after that, you need to 'git-merge' incremental imports, or
31 any CVS branches, yourself. It is advisable to specify a named remote via
32 -r to separate and protect the incoming branches.
38 Verbosity: let 'cvsimport' report what it is doing.
41 The root of the CVS archive. May be local (a simple path) or remote;
42 currently, only the :local:, :ext: and :pserver: access methods
43 are supported. If not given, 'git-cvsimport' will try to read it
44 from `CVS/Root`. If no such file exists, it checks for the
45 `CVSROOT` environment variable.
48 The CVS module you want to import. Relative to <CVSROOT>.
49 If not given, 'git-cvsimport' tries to read it from
53 The git repository to import to. If the directory doesn't
54 exist, it will be created. Default is the current directory.
57 The git remote to import this CVS repository into.
58 Moves all CVS branches into remotes/<remote>/<branch>
59 akin to the 'git-clone' "--use-separate-remote" option.
61 -o <branch-for-HEAD>::
62 When no remote is specified (via -r) the 'HEAD' branch
63 from CVS is imported to the 'origin' branch within the git
64 repository, as 'HEAD' already has a special meaning for git.
65 When a remote is specified the 'HEAD' branch is named
66 remotes/<remote>/master mirroring 'git-clone' behaviour.
67 Use this option if you want to import into a different
70 Use '-o master' for continuing an import that was initially done by
74 Import-only: don't perform a checkout after importing. This option
75 ensures the working directory and index remain untouched and will
76 not create them if they do not exist.
79 Kill keywords: will extract files with '-kk' from the CVS archive
80 to avoid noisy changesets. Highly recommended, but off by default
81 to preserve compatibility with early imported trees.
84 Convert underscores in tag and branch names to dots.
87 Substitute the character "/" in branch names with <subst>
89 -p <options-for-cvsps>::
90 Additional options for cvsps.
91 The options '-u' and '-A' are implicit and should not be used here.
93 If you need to pass multiple options, separate them with a comma.
96 Pass the timestamp fuzz factor to cvsps, in seconds. If unset,
97 cvsps defaults to 300s.
99 -P <cvsps-output-file>::
100 Instead of calling cvsps, read the provided cvsps output file. Useful
101 for debugging or when cvsps is being handled outside cvsimport.
104 Attempt to detect merges based on the commit message. This option
105 will enable default regexes that try to capture the source
106 branch name from the commit message.
109 Attempt to detect merges based on the commit message with a custom
110 regex. It can be used with '-m' to enable the default regexes
111 as well. You must escape forward slashes.
113 The regex must capture the source branch name in $1.
115 This option can be used several times to provide several detection regexes.
118 Skip paths matching the regex.
121 Import all commits, including recent ones. cvsimport by default
122 skips commits that have a timestamp less than 10 minutes ago.
125 Limit the number of commits imported. Workaround for cases where
126 cvsimport leaks memory.
128 -A <author-conv-file>::
129 CVS by default uses the Unix username when writing its
130 commit logs. Using this option and an author-conv-file
134 exon=Andreas Ericsson <ae@op5.se>
135 spawn=Simon Pawn <spawn@frog-pond.org>
139 'git-cvsimport' will make it appear as those authors had
140 their GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL set properly
143 For convenience, this data is saved to `$GIT_DIR/cvs-authors`
144 each time the '-A' option is provided and read from that same
145 file each time 'git-cvsimport' is run.
147 It is not recommended to use this feature if you intend to
148 export changes back to CVS again later with
149 'git-cvsexportcommit'.
152 Print a short usage message and exit.
156 If '-v' is specified, the script reports what it is doing.
158 Otherwise, success is indicated the Unix way, i.e. by simply exiting with
