			reposurgeon - a repository surgeon

reposurgeon enables risky operations that version-control systems don't
want to let you do, such as (a) editing past comments and metadata,
(b) excising commits, (c) coalescing commits, and (d) removing files
and subtrees from repo history. The original motivation for
reposurgeon was to clean up artifacts created by repository
conversions.

reposurgeon is also useful for scripting very high-quality conversions
from Subversion.  It is better than git-svn at tag lifting,
automatically cleaning up cvs2svn conversion artifacts, dealing with
nonstandard repository layouts, recognizing branch merges, handling
mixed-branch commits, and generally at coping with Subversion's many
odd corner cases.  Normally Subversion repos should be analyzed at a
rate of upwards of ten thousand commits per minute.

repodiffer is a program that reports differences between repository 
histories. It uses a diff(1)-like algorithm to identify spans of
identical revisions, and to pick out revisions that have been 
changed or deleted or inserted. It may be useful for comparing the
output of different repository-conversion tools in detail.

Another auxiliary program, repopuller, assists in mirroring Subversion
repositories. 

This distribution also includes a generic Makefile describing a
repeatable conversion workflow using these tools.

Finally, an Emacs Lisp mode with useful functions for editing large 
comment mailboxes is included.

There is an extensive regression-test suite in the test/ directory.
To test the correctness of this software, ensure that pylint
is installed and then type 'make check'.
