# Script to copy over a single file in an opensim archive with the matching contents from Git.
# For legacy reasons, this still says "Git".
# Assumes that both the LSL script in the iar fila and its counterpart in GIT contain a line like the following:
# // SLOODLE LSL Script Git Location: mod/awards-1.0/lsl/xytext_prims/xytext.lsl
# It is intended that this script will be passed the results of a "find" command, allowing us to sync a whole .iar file in one go.
# NB There may be some mistakes in the Git location lines in the iar file - these should turn up the first time we sync.
#
# Example of intended use:
# cd working/sloodle_opensim_iar
# git pull
# find iar/ -name '*.lsl' -exec ../sloodle_development_tools/opensim_sync/syncGITScriptsToIAR.sh {} \;
# git diff iar | more
# # Scan through the changes to make sure they make sense
# git add -a
# git commit -a
# git push

# The name of your sloodle module checkout
SLOODLE_ROOT=../moodle-mod_sloodle
