Add a sample user for the svndump library
The svn-fe tool takes a Subversion dump file as input and produces a fast-import stream as output. This can be useful as a low-level tool in building other importers, or for debugging the vcs-svn library. make svn-fe make svn-fe.1 to test.

=========

NAME
|
||||
----
|
||||
svn-fe - convert an SVN "dumpfile" to a fast-import stream
|
||||
|
||||
SYNOPSIS
|
||||
--------
|
||||
svnadmin dump --incremental REPO | svn-fe [url] | git fast-import
|
||||
|
||||
DESCRIPTION
|
||||
-----------
|
||||
|
||||
Converts a Subversion dumpfile (version: 2) into input suitable for
|
||||
git-fast-import(1) and similar importers. REPO is a path to a
|
||||
Subversion repository mirrored on the local disk. Remote Subversion
|
||||
repositories can be mirrored on local disk using the `svnsync`
|
||||
command.
|
||||
|
||||
INPUT FORMAT
|
||||
------------
|
||||
Subversion's repository dump format is documented in full in
|
||||
`notes/dump-load-format.txt` from the Subversion source tree.
|
||||
Files in this format can be generated using the 'svnadmin dump' or
|
||||
'svk admin dump' command.
|
||||
|
||||
OUTPUT FORMAT
|
||||
-------------
|
||||
The fast-import format is documented by the git-fast-import(1)
|
||||
manual page.
|
||||
|
||||
NOTES
|
||||
-----
|
||||
Subversion dumps do not record a separate author and committer for
|
||||
each revision, nor a separate display name and email address for
|
||||
each author. Like git-svn(1), 'svn-fe' will use the name
|
||||
|
||||
---------
|
||||
user <user@UUID>
|
||||
---------
|
||||
|
||||
as committer, where 'user' is the value of the `svn:author` property
|
||||
and 'UUID' the repository's identifier.
|
||||
|
||||
To support incremental imports, 'svn-fe' will put a `git-svn-id`
|
||||
line at the end of each commit log message if passed an url on the
|
||||
command line. This line has the form `git-svn-id: URL@REVNO UUID`.
|
||||
|
||||
Empty directories and unknown properties are silently discarded.
|
||||
|
||||
The resulting repository will generally require further processing
|
||||
to put each project in its own repository and to separate the history
|
||||
of each branch. The 'git filter-branch --subdirectory-filter' command
|
||||
may be useful for this purpose.
|
||||
|
||||
BUGS
|
||||
----
|
||||
Litters the current working directory with .bin files for
|
||||
persistence. Will be fixed when the svn-fe infrastructure is aware of
|
||||
a Git working directory.

||||
