Reloader can accelerate web development by automatically refreshing your pages (in multiple browsers) when a file is locally modified. If a css file is modified, only stylsheets are reloaded.

$ pip install twisted
$ pip install pyinotify

• the rest should already be installed

Start the server:

$ python reloader.py --path /var/www/projectdir/ --strict

Add this tag to your html:

<script type="text/javascript" src="http://127.0.0.1:8181/js"></script>

usage: reloader.py [-h] [-p PATH] [-s] [-v]

optional arguments:
  -h, --help            show this help message and exit
  -p PATH, --path PATH  the directory to monitor
  -s, --strict          only watch: css xml html php js asp png jpeg jpg gif
  -v, --verbose

• chrome 11
• internet explorer 7

I wrote this several years ago and better alternatives now exist.
