       cvs2svn - convert a cvs repository into a subversion repository

       cvs2svn [OPTION]... --options=PATH

       Create  a new Subversion repository based on the version history stored
       in a CVS repository. Each CVS commit will be mirrored in the Subversion
       repository,  including such information as date of commit and id of the

       CVS-REPOS-PATH is the filesystem path of the part of the CVS repository
       that  you want to convert.  It is not possible to convert a CVS reposi-
       tory to which you only have remote access; see the FAQ for more  infor-
       mation.   This path doesn't have to be the top level directory of a CVS
       repository; it can point at a project within  a  repository,  in  which
       case only that project will be converted.  This path or one of its par-
       ent directories has to contain a subdirectory  called  CVSROOT  (though
       the CVSROOT directory can be empty).

       Multiple  CVS  repositories  can  be converted into a single Subversion
       repository in a single run of cvs2svn, but only by using  an  --options

              Read  the  conversion options from path instead of from the com-
              mand line.  This option allows far more  conversion  flexibility
              than can be achieved using the command-line alone.  See the doc-
              umentation for more information.  Only  the  following  command-
              line   options   are  allowed  in  combination  with  --options:
              -h/--help, --help-passes, --version,  -v/--verbose,  -q/--quiet,
              -p/--pass/--passes, --dry-run, and --profile.

       -s, --svnrepos path
              Write  the output of the conversion into a Subversion repository
              located at path.  This option causes a new Subversion repository
              to  be  created at path unless the --existing-svnrepos option is
              also used.

              Load the converted CVS repository into  an  existing  Subversion
              repository,  instead of creating a new repository.  (This option
              should be used in combination with -s/--svnrepos.)  The  reposi-
              tory  must either be empty or contain no paths that overlap with
              those that will result from the conversion.   Please  note  that
              you need write permission for the repository files.

              Pass  --fs-type=type  to  "svnadmin  create" when creating a new

              Pass --bdb-txn-nosync to "svnadmin create" when creating  a  new
              BDB-style Subversion repository.

              Just  produce  a  dumpfile;  don't  commit to an SVN repository.
              Write the dumpfile to path.

              Do not create a repository or a dumpfile; just print the details
              of  what  cvs2svn  would  do  if  it were really converting your

              Convert only trunk commits, not tags nor branches.

              Set the top-level path to use for trunk in the Subversion repos-
              itory.  The default is trunk.

              Set  the  top-level  path  to use for branches in the Subversion
              repository.  The default is branches.

              Set the top-level path to use for tags in the Subversion reposi-
              tory.  The default is tags.

              When  all  files  are deleted from a directory in the Subversion
              repository, don't delete the empty directory (the default is  to
              delete any empty directories.

              Use  encoding  as  the encoding for filenames, log messages, and
              author names in the CVS repos.  This  option  may  be  specified
              multiple  times,  in which case the encodings are tried in order
              until     one     succeeds.       Default:      ascii.       See
              http://docs.python.org/lib/standard-encodings.html for a list of
              other standard encodings.

              If none of the encodings specified with  --encoding  succeed  in
              decoding  an author name or log message, then fall back to using
              encoding in lossy 'replace' mode.  Use of this option may  cause
              information to be lost, but at least it allows the conversion to
              run to completion.  This option only affects the encoding of log
              messages  and  author  names;  there is no fallback encoding for
              filenames.  (By using an --options file, it is possible to spec-
              ify a fallback encoding for filenames.)  Default: disabled.

              Transform RCS/CVS symbol names before entering them into Subver-
              sion.  pattern is  a  Python  regexp  pattern  that  is  matches
              against  the  entire  symbol  name; replacement is a replacement
              using Python's regexp reference syntax.   You  may  specify  any
              number of these options; they will be applied in the order given
              on the command line.

              Read symbol conversion hints from path.  The format of  path  is
              the  same  as the format output by --write-symbol-info, namely a
              text file with four  whitespace-separated  columns:  project-id,
              symbol,  conversion,  and  parent-lod-name.   project-id  is the
              numerical ID of the project to which the symbol belongs,  count-
              ing from 0.  project-id can be set to '.' if project-specificity
              is not needed.  symbol-name is the  name  of  the  symbol  being
              specified.   conversion  specifies how the symbol should be con-
              verted, and can  be  one  of  the  values  'branch',  'tag',  or
              'exclude'.  If conversion is '.', then this rule does not affect
              how the symbol is converted.  parent-lod-name is the name of the
              symbol from which this symbol should sprout, or '.trunk.' if the
              symbol should sprout from trunk.  If parent-lod-name is  omitted
              or  '.',  then this rule does not affect the preferred parent of
              this symbol.  The file may contain blank lines or comment  lines
              (lines whose first non-whitespace character is '#').

              Force  symbols  whose names match regexp to be branches.  regexp
              must match the whole symbol name.

              Force symbols whose names match regexp to be tags.  regexp  must
              match the whole symbol name.

              Exclude branches and tags whose names match regexp from the con-
              version.  regexp must match the whole symbol name.

              Specify how to convert ambiguous symbols (those that  appear  in
              the  CVS  archive  as  both  branches  and  tags).   opt must be
              `heuristic' (decide how to treat each ambiguous symbol based  on
              whether it was used more often as a branch/tag in CVS), `strict'
              (no default; every ambiguous symbol has to be resolved  manually
              using   --force-branch,  --force-tag,  or  --exclude),  `branch'
              (treat every ambiguous symbol as  a  branch),  or  `tag'  (treat
              every ambiguous symbol as a tag).  The default is `heuristic'.

              Prevent  the  creation  of  SVN  commits  that  affect  multiple
              branches or trunk and a branch.  Instead, break such  changesets
              into multiple commits, one per branch.

              If  a  file  appears  both  inside  an outside of the CVS attic,
              retain the attic version in an SVN subdirectory called  `Attic'.
              (Normally this situation is treated as a fatal error.)

              Set  the default username to name when cvs2svn needs to generate
              a commit for which CVS does not record  the  original  username.
              This happens when a branch or tag is created.  The default is to
              use no author at all for such commits.

              Record CVS revision numbers as file properties in the Subversion
              repository.   (Note  that  unless  it is removed explicitly, the
              last CVS revision number will remain associated  with  the  file
              even after the file is changed within Subversion.)

              Specify  an  apache-style  mime.types file for setting svn:mime-

              For files that don't have the kb expansion mode but have a known
              mime  type,  set the eol-style based on the mime type.  For such
              files, set svn:eol-style to "native" if  the  mime  type  begins
              with "text/", and leave it unset (i.e., no EOL translation) oth-
              erwise.  Files with unknown mime types are not affected by  this
              option.   This  option  has  no  effect  unless the --mime-types
              option is also specified.

              Specify a file in the format of Subversion's config file,  whose
              [auto-props]  section can be used to set arbitrary properties on
              files in the Subversion repository  based  on  their  filenames.
              (The [auto-props] section header must be present; other sections
              of the config file, including the enable-auto-props setting, are
              ignored.)   Filenames are matched to the filename patterns case-

              Set svn:eol-style to style for files that  don't  have  the  CVS
              `kb'  expansion  mode  and  whose  end-of-line  translation mode
              hasn't been determined by one of the other options.  style  must
              be `binary' (default), `native', `CRLF', `LF', or `CR'.

              By default, cvs2svn sets svn:keywords on CVS files to "author id
              date" if the mode of the RCS file in question is either kv,  kvl
              or  unset.   If  you use the --keywords-off switch, cvs2svn will
              not set svn:keywords for any file.  While this  will  not  touch
              the  keywords in the contents of your files, Subversion will not
              expand them.

              Use internal code to extract revision contents.  This is  up  to
              50%  faster than using --use-rcs, but needs a lot of disk space:
              Roughly the size of your CVS repository plus the peak size of  a
              complete  checkout  of  the  repository  with  all branches that
              existed and still had commits pending at  a  given  time.   This
              option is the default.

              Use RCS 'co' to extract revision contents.

              Use  CVS  to  extract revision contents (only use this if having
              problems with --use-internal-co or --use-rcs, as  those  options
              are much faster).

              Set  the path to use for temporary data.  Default is a directory
              called cvs2svn-tmp under the current directory.

              Path to the svnadmin program.   (svnadmin  is  needed  when  the
              -s/--svnrepos output option is used.)

              Path  to  the co program.  (co is needed if the --use-rcs option
              is used.)

              Path to the cvs program.  (cvs is needed if the --use-cvs option
              is used.)

              Path to the GNU sort program.  (cvs2svn requires GNU sort.)

       -p, --pass pass
              Execute only pass pass of the conversion.  pass can be specified
              by name or by number (see --help-passes).

       -p, --passes [start]:[end]
              Execute passes start through end of the conversion  (inclusive).
              start and end can be specified by name or by number (see --help-
              passes).  If start or end is missing, it defaults to  the  first
              or last pass, respectively.  For this to work the earlier passes
              must have been completed before on the same CVS repository,  and
              the generated data files must be in the temporary directory (see

              Print the version number.

       -h, --help
              Print the usage message and exit with success.

              Print the numbers and names of the conversion  passes  and  exit
              with success.

       -v, --verbose
              Print more information while running.  This option may be speci-
              fied twice to output voluminous debugging information.

       -q, --quiet
              Print less information while running.  This option may be speci-
              fied twice to suppress all non-error output.

              Write  symbol  statistics and information about how symbols were
              converted to path during CollateSymbolsPass.

              Prevent the deletion of temporary files.

              Profile with 'hotshot' (into file cvs2svn.hotshot).

       A directory called cvs2svn-tmp (or the directory specified by --tmpdir)
       is used as scratch space for temporary data files.
