# xsm

xsm is a session manager.
A session is a group of applications, each of which has a particular state.
xsm allows you to create arbitrary sessions - for example, you might have a "light" session, a "development" session, or an "xterminal" session.
Each session can have its own set of applications.
Within a session, you can perform a "checkpoint" to save application state, or a "shutdown" to save state and exit the session.
When you log back in to the system, you can load a specific session, and you can delete sessions you no longer want to keep.

Some session managers simply allow you to manually specify a list of applications to be started in a session.
xsm is more powerful because it lets you run applications and have them automatically become part of the session.
On a simple level, xsm is useful because it gives you this ability to easily define which applications are in a session.
The true power of xsm, however, can be taken advantage of when more and more applications learn to save and restore their state.
