What do you think of adding a SEE_ALSO variable in the pkgs Makefiles,
which would describe, for each package, other packages related to it?
Just like the section of man pages of the same name, it would allow users
to be aware of all the alternate packages that could be useful, at a
glance, and before installing or unpacking anything. And very otfen, man
pages for various softwares do not provide this information at all.

For instance, I was looking a few days ago for an alternative to
latex2html, but I did not know where to search exactly, and I was obliged
to look to the 'DESCR' file of many packages, in many directories (print,
converters, textprocs). Finally I got the information with google and
came back to pkgsrc afterward. Package names are not always
self-explanatory :)

The SEE_ALSO variable is not an 'absolutely needed feature' (there are
many ways to find the information elsewhere), but it could be great to
have it.
