## CVS Tags 

When obtaining or updating sources from  **cvs**  and  **CVSup**  a revision tag (reference to a date in time) must be specified.

A revision tag refers to either a particular line of DragonFly development, or a specific point in time. The first type are called ***branch tags***, the second type are called ***release tags***.

### Branch Tags 

The DragonFly tree has no branch tags at the current time.

### Release Tags 

These tags correspond to the DragonFly `src/` tree at a specific point in time, when a particular version was released.

 **HEAD:** 
The latest bleeding-edge DragonFly code. Be warned that this is considered unstable and possibly may not build or compile at any time.

 **DragonFly_Preview:**  A "preview" of the latest bleeding-edge DragonFly code. The main purpose of the Preview tag is to support those users who want a fairly recent snapshot at a "reasonably stable" point in development. Under normal conditions, one should consider syncing Preview at least once a month.

 **DragonFly_RELEASE_X_YY:**  DragonFly Release Version X.YY
