# Commentary:
|
|
|
|
# This script is a replacement for `git submodule update'. The
|
|
# main differences are that this script resets the current branch
|
|
# if necessary instead of detaching HEAD and that it is capable of
|
|
# adding and configuring additional remotes.
|
|
|
|
# The following variables can be set in ".gitmodules":
|
|
#
|
|
# * submodule.DRONE.remote = NAME URL
|
|
#
|
|
# This variable specifies an additional remote named DRONE that is
|
|
# fetched from URL.
|
|
#
|
|
# * borg.collective = REMOTE
|
|
#
|
|
# This variable specifies the name used for remotes that reference
|
|
# a repository that has been patched by the collective. If a NAME
|
|
# matches REMOTE, then it is configured as the upstream of the
|
|
# current branch of the respective DRONE.
|
|
#
|
|
# * borg.pushDefault = DEFAULT
|
|
#
|
|
# This variable specifies a name used for push-remotes. If a NAME
|
|
# matches DEFAULT, then it is configured as the push-remote of the
|
|
# current branch of the respective DRONE.
|
|
|
|
# If an error occurs while `make bootstrap' runs this script, then
|
|
# fix the error(s) and run `bin/borg-bootstrap' directly, followed
|
|
# by `make build'.
