[Qemu-devel] [PATCH] add a SNAPSHOT flag to be able to generate snapshots from CVS

Greetings,

The following patch adds a "SNAPSHOT" variable to the Makefile which can be
changed to "yes" (or any other value) so that `make -k tar` generates a
snapshot tar (on a configured or not CVS tree) instead of a release source tar
(useful when debugging a version of the CVS tree) by using a generated version 
based on the current date through GNU date.

Only the name of the tar is changed so to keep all internal logic that relies
in the version unchanged.

Carlo
