#
# Target to provide a mechanism of package uploading, as well as
# pushing changes from a local git repo to the main repo.
#
# This target depends on commit in case anything else needs to be
# committed.
#
# We do a git check first as part of the "dist" target, so that if it
# fails for some reason it needs to be resolved before the package
# upload.  Note that before we can push the changes to the main
# repository, we first need to do a "git pull". In case there are
# changes to other unrelated packages, we do a "git stash" before the
# pull followed by "git stash pop" after the push to revert those
# changes. However, if the "git pull" brought in some changes to one
# of these locally changed packages, you may get a merge conflict that
# needs to be resolved when the stash is re-applied. The
# re-application of the stash will not be fatal so that uploadsas may
# continue. Go and fix the files that "git stash pop" complained
# about, and then run "git stash drop" to remove the broken stash from
# the internal stack. Of course, the initial "git pull" may also
# reveal conflicts if two developers are working on the same package
# at the same time. This conflict will be fatal, requiring a
# resolution before things can continue.
#
# Use SASBIN instead of SASBINDEV so one can upload package sas itself
#

# Target to provide a mechanism to commit to the git repo.
#
# Since moving to git from CVS, the main difference is that changes
# are only committed to the local repository. The synchronization with
# the remote master is part of the "upload" target. Tagging is now
# part of the "dist" target.
#
# Commits are made to the local master branch. By default only modified
# files in the current package are committed. Files that weren't previously
# in the index need to be added with "git add".
