Features:
- Can be used as a drop-in replacement for cron.

- Secure communications between master servers and clients.
- Cluster-able: Master can automatically fail over so any number of secondary masters.
- Ajax web interface for better monitoring and execution feedback.
- Graphing/Reporting: Visualize the running duration and timing of your jobs.
- Run Jobs based on File Triggers
Installation:
Point your web server to the 'web' directory that is under scheduler/. If you installed in /opt/scheduler, then an example apache entry would be:
Alias /scheduler/ /opt/scheduler/web/
<Directory /opt/scheduler/web/>
AuthType Basic
AuthName "DS_SChed"
AuthUserFile /opt/scheduler/.htpasswd
require valid-user
</Directory>
Secure your site by using SSL and htpasswd. You can run root processes with the scheduler to restricting access is highly recommended.
Creating an htpasswd file:
htpasswd -c /opt/scheduler/.htpasswd <user>

TO DO:
- Not every feature on the web interface works yet. Anyone who knows web development could probably do better. Patches are welcome.
- Need to add ON_NEWFILE trigger. Done
- Need to add ON_FILECHANGE trigger.
- Need better reporting/graphing flexibility.
- Need Translations
