Double Compilation?

# double compilation support
Advocate: Martin Zobel-Helas and Luk Claes
Description: All packages should be able to be built twice in a
row.
Bug-User: debian-qa@lists.debian.org
Bug-Tag: qa-doublebuild
Bug-Url: http://bugs.debian.org/cgi-bin/pkgrepor ... oublebuild
State: confirmed

What does this really mean? Why is it important to compile twice? If you compile once, wouldn't it comile a second time?

Help me to understand.

If it doesn't clean up after itself the build may fail on repeated attempts and it is considered a FTBFS (failure to build from source) bug....

I think it means that you should be able to run fakeroot debian/rules binary twice without having to clean the source tree inbetween with fakeroot debian/rules clean.
I am currently a Debian Maintainer. I am also in the New Maintainers' Queue.
