>Description:

web2c ships (among other more useful things) these six man pages:

man/man1/dvilualatex-dev.1
man/man1/lualatex-dev.1
man/man1/pdflatex-dev.1
man/man1/platex-dev.1
man/man1/uplatex-dev.1
man/man1/xelatex-dev.1

which each contain only ".so man1/latex-dev.1" (that is, they're roff
legacy symlinks)

...but does not ship latex-dev.1, and neither does anything else in
pkgsrc.

These cause makewhatis to complain (how I noticed) and since they're
useless they should probably be removed from the package.

>How-To-Repeat:

Inspection.

>Fix:

Would like input from the maintainer before I go mucking with web2c's
build... among other things I have no idea what they're supposed to be
documenting as there are no such bins in the package either.
