# A small wrapper around the output of the 'rsync' command, adding colors for interesting parts.
# Can be save to ~/bin/CP for example (or anywhere in your path).
#
# Perfect replacement for 'cp', notable improvement are:
# - the ability to copy to and from distant location (if it is reachable by SSH),
# - print the current file transfer (when file is sent, not continuously updated, but rsync is able to, I could improve)
# - exclude .git by default (if it exists)
# - follow your .gitignore files to exclude files untracked by your current Git folder (if it exists)
# - WARNING: this means that a well written .gitignore for LaTeX projects will NOT send the PDF!
# - it pretty prints in full ANSI colors to highlight different information of rsync!
# - optional: notify-send when copy is done! (just uncomment last line)
# - logs the command to /tmp/CP.log, in case you want to find again what you sent 3h ago
#
# More features!
# - You can use this script in your Makefile, to add rules to send files over the network easily:
#SHELL=/usr/bin/env /bin/bash
#send_zamok:
#	CP ./ ${Szam}bin/
