# Example ../ChangePackage gnu

# This would change all the files from javax to gnu.

# Bash was assumed when this script was writting.  With luck it will work

#
# More sanity checks could be made but just move the script to the
# directory above rxtx-version,  then cd to .../rxtx-version.  Finally
# call ../ChangePackage javax gnu or the reverse.
