convert: some tidyups, doc improvements, and test fixes
The various back end options are now documented.
The hg source can now be configured not to hand out a revision ID.
hg convert [OPTION]... SOURCE [DEST [MAPFILE]]
Convert a foreign SCM repository to a Mercurial one.
Accepted source formats:
- Mercurial
- CVS
- Darcs
- git
- Subversion
Accepted destination formats:
- Mercurial
- Subversion (history on branches is not preserved)
If no revision is given, all revisions will be converted. Otherwise,
convert will only import up to the named revision (given in a format
understood by the source).
If no destination directory name is specified, it defaults to the
basename of the source with '-hg' appended. If the destination
repository doesn't exist, it will be created.
If <MAPFILE> isn't given, it will be put in a default location
(<dest>/.hg/shamap by default). The <MAPFILE> is a simple text
file that maps each source commit ID to the destination ID for
that revision, like so:
<source ID> <destination ID>
If the file doesn't exist, it's automatically created. It's updated
on each commit copied, so convert-repo can be interrupted and can
be run repeatedly to copy new commits.
The [username mapping] file is a simple text file that maps each source
commit author to a destination commit author. It is handy for source SCMs
that use unix logins to identify authors (eg: CVS). One line per author
mapping and the line format is:
srcauthor=whatever string you want
The filemap is a file that allows filtering and remapping of files
and directories. Comment lines start with '#'. Each line can
contain one of the following directives:
include path/to/file
exclude path/to/file
rename from/file to/file
The 'include' directive causes a file, or all files under a
directory, to be included in the destination repository, and the
exclusion of all other files and dirs not explicitely included.
The 'exclude' directive causes files or directories to be omitted.
The 'rename' directive renames a file or directory. To rename from a
subdirectory into the root of the repository, use '.' as the path to
rename to.
