[tex-live] TLCore packages

[texlive at schoepfer.info]

Hi,

when compiling from source, tools like a2ping,afm2pl + accompaniment 
files ... are installed, which is all fine for binary files.
These packages(including their accompaniment files) also exist in the 
netarchives, in texlive.tlpdb tagged as TLCore, but there are also 
packages(e.g. hyphen-packages) tagged as TLCore which are not present in 
the texlive source tarball.
For packagers, the accompaniment files are partly overlapping, as the 
netarchive from some packages have not the same content/filenames.

I'm looking for a way to use either the accompaniment files from 
sourceinstall or from the netarchive.
Just overwriting with netarchive files may lead to unused files or 
duplicated files.
Thanks for any hints.

Btw. a2ping from the source tarball does not install the manpage, which 
is present in a2ping.doc.tar.xz
