# This script pulls the current branch, then walks the first parents and
|
|
# commit each of them into subversion.

# The subversion repository must not be taking any external commit or this
|
|
# script will erase them. This script cannot run off a bare repository.
|
|
#
|
|
# *** INITIAL SETUP ***
|
|
#
|
|
# 1. Run this command line to get the repository up and ready for this script:
|
|
#
|
|
# $ cd /path/to/repo/; git log -1 --pretty=format:%H >.git/git2svn.last_commit_hash
|
|
#
|
|
# 2. Configure the lines below... $ENV{'GIT_DIR'} must point to the .git
|
|
# directory of the git-svn repo.
|
|
#
