# Shell script to make a diff file of apcupsd
# for submission to Riccardo
#
# Called:  ./makediff <base-directory-from-last-snapshot>
# 
# It assumes that it is called from the parent directory
# of your work directory (new) and the base directory.
#
# It makes a copy of the base directory, makes a copy
# of your current work directory (new), then cleans
# up a lot of files in those directories. Any file
# named "developer"s* will be deleted. This allows me
# to create files such as kernsxxx in the main directory 
# without worrying that they will appear in the diff.
# Finally, it does a diff of the two directories putting
# and prints the output name. The original base
# directory specified on the call line and your
# work directory are not modified in any way.
#
#  example of actuall call: ./makediff apcupsd-3.7.1-beta1
#
# developer -- put your name here
developer="kern"
# new -- name of updated directory with your changes
new="k"
#
# temp base directory, no need to change
base="apcupsd-3.7.1"
#
