 LinuxPA is a try to bring a [PortableApps.com](http://portableapps.com) type launcher to Linux.

 # PortableApps.com Compatibility
 LinuxPA works will with the PortableApps.com launcher, as it looks for apps in the PortableApps folder and grabs the app's name and icon from where it should be in the PortableApps.com format.

 Right now AppImages are simply supported via the native linux executable support, but later I'm hoping to add downloading and automatic updating support later on.
