# Watch paths (given as arguments), automatically build when something changes.
# The script does a couple opinionated things to make my life easier:
#
#  * Terminal scrollbuffer is reset before each iteration, simplifying scrolling.
#  * I use a filter script to colorize gcc output (clang errors would be nicer).
#  * Output is copied to a log file (/tmp/build.log).
#    - I open this file in Sublime or vim, which reloads the file on change (each build).

# To use, pipe your HAProxy log with timing information (like "0/0/1/1/3 200") to 
# this script.  It will output min, max, med, avg and a latency distribution graph.
