# Bazaar GSoC Zipper
# I basically wrote this script to generate diff files for my project
# from parent banch (which is `vita` for me ), for most of you it will
# be `trunk`, just get a fresh copy of trunk and run this script inside it.
# Ex:
#
# Step 1: Get a fresh copy of trunk
# $ bzr branch lp:sahana-eden eden
# $ cd eden
#
# Step 2: Move this script into the trunk
# $ mv ~/Downloads/bzr-gsoc-zipper.sh .
#
# Step 3: Just modify variables `revisions`, `branch`, `student_name` 
# $ emacs bzr-gsoc-zipper.sh
#
# Step 4: execute the script
# $ bash bzr-gsoc-zipper.sh
#
# Step 5: Save the tarball and cleanup
# $ cp Given_Name_Surname.tar.gz ~/
# $ rm bzr-gsoc-zipper.sh*
#

# > Enter Your Revisions
revisions=( 1583 1663 1664 1665 1716 1718 1746 1773 1824 1840 )

# > Enter Branch Name
branch="trunk"
# > Enter Student Name from melange profile
student_name="Given_Name_Surname"
