automatically modifying scriptlets (included files) at package build time

Hello,
I would like to know if there is a way to do this:
<eddyp_work> is there a way to generate the maintainer scripts out
of .in scriptlets, at build time (i.e. use templates for the maintainer
scriptlets and run some tool to generate the ones that should end up in
the package)
<f13> eddyp_work: that gets in the way of scripted rebuilds and such
<eddyp_work> f13: why would it?
<f13> eddyp_work: because scripts expect a .spec file, not a .spec.in
<eddyp_work> f13: spec files can use includes....
<eddyp_work> f13: I was thinking of generating those before the
package build; something like a configure stage, but for the package
itself
<f13> eddyp_work: *shrug* would be worth posting to fedora-devel-list
with an example of what you want to do
<eddyp_work> f13: debian can do that in the debian/rules file
<eddyp_work> f13: I want to be able to have a variable set in the
scripts with some contents that is got from the source
<eddyp_work> s/scripts/maintainer scriptlets/
The main idea is that I am maintaing the packages for our antivirus
product and we have some automated builder for the packages and the
upstream part of the packages.
There can be multiple releases/day of the upstream package and the rpm
packages are updated automatically to follow the upstream packages'
versions.
Now, here follows the tricky part, so please pay attention: the upstream
package itself contains some file that specifies the version of the
package (we needed this to be able to tell which version over which
version we're upgrading/installing, since rpm doesn't pass this
information to the {pre,post}{,rm} scripts).
(I am using includes already and have the scriptlets separated into
scripts.)
So the thing is that the file in the package can have a different
version than the one of the package or the tarball, so the scripts need
to use/know the version that is placed in the files themselves.
That's why I need some kind of configuration step of the package that
can be always ran after the package was unpacked, but before the package
is generated so I can generate the scriptlets with the filled
information so the upgrade part works correctly.
Is rpm able to do such a thing?
