# The output of this script is a splicemap.
|
|
#
|
|
# A splicemap is used by the mercurial 'convert' extension to direct its
|
|
# splicing operation.
|
|
#
|
|
# The script assumes you already have a destination repository
|
|
# containing a conversion somewhere in its history, but that you've
|
|
# possibly mixed some new commits on top of that conversion. It outputs
|
|
# a splicemap that picks up the conversion where it left off (with the
|
|
# first descendant, in the source repo, of the src rev given by --start,
|
|
# if or rather the first descendant that would be included by the
|
|
# conversion's filemap) and connects them to the current tip of the
|
|
# destination repo.
