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.
34 If you intend to set up a shared public repository that all developers can
35 read/write, or if you want to use linkgit:git-cvsserver[1], then you
36 probably want to make a bare clone of the imported repository,
37 and use the clone as the shared repository.
38 See linkgit:gitcvs-migration[7].
44 Verbosity: let 'cvsimport' report what it is doing.
47 The root of the CVS archive. May be local (a simple path) or remote;
48 currently, only the :local:, :ext: and :pserver: access methods
49 are supported. If not given, 'git-cvsimport' will try to read it
50 from `CVS/Root`. If no such file exists, it checks for the
51 `CVSROOT` environment variable.
54 The CVS module you want to import. Relative to <CVSROOT>.
55 If not given, 'git-cvsimport' tries to read it from
59 The git repository to import to. If the directory doesn't
60 exist, it will be created. Default is the current directory.
63 The git remote to import this CVS repository into.
64 Moves all CVS branches into remotes/<remote>/<branch>
65 akin to the 'git-clone' "--use-separate-remote" option.
67 -o <branch-for-HEAD>::
68 When no remote is specified (via -r) the 'HEAD' branch
69 from CVS is imported to the 'origin' branch within the git
70 repository, as 'HEAD' already has a special meaning for git.
71 When a remote is specified the 'HEAD' branch is named
72 remotes/<remote>/master mirroring 'git-clone' behaviour.
73 Use this option if you want to import into a different
76 Use '-o master' for continuing an import that was initially done by
80 Import-only: don't perform a checkout after importing. This option
81 ensures the working directory and index remain untouched and will
82 not create them if they do not exist.
85 Kill keywords: will extract files with '-kk' from the CVS archive
86 to avoid noisy changesets. Highly recommended, but off by default
87 to preserve compatibility with early imported trees.
90 Convert underscores in tag and branch names to dots.
93 Substitute the character "/" in branch names with <subst>
95 -p <options-for-cvsps>::
96 Additional options for cvsps.
97 The options '-u' and '-A' are implicit and should not be used here.
99 If you need to pass multiple options, separate them with a comma.
102 Pass the timestamp fuzz factor to cvsps, in seconds. If unset,
103 cvsps defaults to 300s.
105 -P <cvsps-output-file>::
106 Instead of calling cvsps, read the provided cvsps output file. Useful
107 for debugging or when cvsps is being handled outside cvsimport.
110 Attempt to detect merges based on the commit message. This option
111 will enable default regexes that try to capture the source
112 branch name from the commit message.
115 Attempt to detect merges based on the commit message with a custom
116 regex. It can be used with '-m' to enable the default regexes
117 as well. You must escape forward slashes.
119 The regex must capture the source branch name in $1.
121 This option can be used several times to provide several detection regexes.
124 Skip paths matching the regex.
127 Import all commits, including recent ones. cvsimport by default
128 skips commits that have a timestamp less than 10 minutes ago.
131 Limit the number of commits imported. Workaround for cases where
132 cvsimport leaks memory.
134 -A <author-conv-file>::
135 CVS by default uses the Unix username when writing its
136 commit logs. Using this option and an author-conv-file
140 exon=Andreas Ericsson <ae@op5.se>
141 spawn=Simon Pawn <spawn@frog-pond.org>
145 'git-cvsimport' will make it appear as those authors had
146 their GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL set properly
149 For convenience, this data is saved to `$GIT_DIR/cvs-authors`
150 each time the '-A' option is provided and read from that same
151 file each time 'git-cvsimport' is run.
153 It is not recommended to use this feature if you intend to
154 export changes back to CVS again later with
155 'git-cvsexportcommit'.
158 Print a short usage message and exit.
162 If '-v' is specified, the script reports what it is doing.
164 Otherwise, success is indicated the Unix way, i.e. by simply exiting with
