generating release package from snapshot package

[Nathan Ridge]

Hello,
 
I understand there are several differences between the format
of release packages (e.g. ftp://gcc.gnu.org/pub/gcc/releases/gcc-4.6.1/)
and snapshot packages (e.g. ftp://gcc.gnu.org/pub/gcc/snapshots/LATEST-4.7):
 
 - the release packages are divided into components (core, language frontends,
   test suite) while in the snapshot package everything is in one place
 - the release packages have some generated files (by Flex and Texinfo)
   that the snapshot packages do not
 
How would I go about preparing a package of the release format from
a package of the snapshot format?
 
Thanks,
Nate
