Hi
It is fairly trivial to make a metapackage sagemath-data which depends on all the sagemath-data-* sub-packages.
I have some idea how to make "binary" packages, e.g. I repackage sagemath into a PPA by simply unpacking the files, so nothing is really built. There must be many *-doc packages in or *-data pacakges in debian that will show you how to do this with best practice.
It looks like aptdaemon-data is really small and simple (apt-get source aptdaemon-data) and a good example with a very simple rules file. It uses files ending in .install in the debian directory to list files to install. The rules file contains something like
%:
dh $@
override_dh_auto_configure:
override_dh_auto_build:
override_dh_auto_install:
override_dh_auto_clean:
override_dh_auto_test:
override_dh_shlibdeps:
which is what I use to simply repackage files without building, i.e. without compiling coed during debuild. Everything is just installing files.
Regards,
Jan
