[cygport] REQUIRES_EXCLUDE_FROM

[Marco Atzeri]

Hi Jon,

I just found on one of the python cygport's I took from Yaakov
the usage of REQUIRES_EXCLUDE_FROM, but the documentation
has nothing about it.
I think will be useful to add some info on documentation before we waste
time reinventing the wheel to remove "unwanted/optional" dependencies

$ grep -rH REQUIRES_EXCLUDE .
./lib/pkg_info.cygpart: for d in ${REQUIRES_EXCLUDE_FROM//:/ }

it is used in the "__list_deps() " function
-----------------------------------------------------
     for d in ${REQUIRES_EXCLUDE_FROM//:/ }
     do
         deps_prune+=" -o -path ${d#/} -prune"
     done
-----------------------------------------------------


Additional issue:
the cygport package page
https://cygwin.com/packages/summary/cygport-src.html

is reporting www.cygwin.com as Homepage , but should not be
https://cygwin.com/git/cygwin-apps/cygport.git  ?

It took some moments to find the repository

Regards
Marco
