NAME
    svn_mirror_externals.sh

SYNOPSIS
    $ /path/to/svn_mirror_externals.sh --url=http://you.com/svn --init [...]
    $ /path/to/svn_mirror_externals.sh [--url=http://you.com/svn] [--time]
    $ $GIT_DIR/mirror-externals/apply-externals
    $ $GIT_DIR/mirror-externals/rearrange-heads
    $ $GIT_DIR/mirror-externals/reparent-heads
    $ $GIT_DIR/mirror-externals/convert-tags
  
USAGE
    Run this script from an empty directory (which will become a git
    repository).

    If you want to pass extra flags to git-svn fetch, eg --authors-file, add
    them after the --init. The URL has to be the publically accessible
    one that you used when creating the svn:external references. You *might*
    be able to do the init command from a different URL, but this is untested.
    The URL is only strictly required for the --init call. --time is vaguely
    interesting for timing how long certain phases of the import take.
    
    You can run the phases individually if you want (useful for debugging)

PHASES
    apply-externals:
        This phase detects all the svn:externals present in the repository
        and propagates changes in the source objects to the directory
        containing the svn:externals reference. This is done on a
        commit-by-commit basis, so changesets on the external are propagated
        individually (not squashed.) The only case where changes on the
        external are squashed is on the first commit containing the external
        reference.
        
    rearrange-heads:
        This pass locates all individual "projects" in the repository
        (subdirectories conforming to the standard svn layout) and converts
        them to individual git heads (branches)
        
    reparent-heads:
        This pass attempts to determine the ancestry of each branch in order
        to recreate merge history. Only the creation point of the (svn) branch
        is handled, later merge commits are not.
        
    convert-tags:
        This pass converts any svn tags/ branches to git tags.
        
    
KNOWN LIMITATIONS
    This script will almost assuredly die horribly if your repo has any paths
    with spaces (or other funky control characters) in them.

    This script depends on the GNU userland (grep, probably others)

    This script works on my repository. It might on yours too!
