Installation of Paste-enabled applications is consistent and reliable; you don't have to understand what technologies those applications used. Paste-enabled applications are installable with easy_install, like:
$ easy_install FileBrowser ... messages ...
Once an application is installed, you can set up an instance of that application with paste deploy:
$ paste deploy FileBrowser location ... @@: make this work ;) ...
This just wrote to location/filebrowser.ini -- you can configure the application there, with whatever specifics that application needs. Then you can integrate it into your website and other applications, with a file like:
[composit:main] use = egg:Paste#urlmap /browser = config:filebrowser.ini
You can attach applications to many locations using this. Once you've set that file up with your local settings and preferences, you can run:
$ paster serve location/apps.ini --daemon
And it will be running in the background.
