# htmlreload
# When an HTML or CSS file changes, reload any visible browser windows.
# Usage:
# 
#     htmlreload [ --browsername ] [ files ... ]
#
# If no files to watch are specified, all files (recursively) in the
# current working directory are monitored. (Note: this can take a long
# time to initially setup if you have a lot of files).
#
# An argument that begins with a dash is the browser to control.
# `htmlreload --chrom` will match both Chromium and Chrome.
