Patch originally from https://sources.debian.net/patches/erlang/1:20.0.1%2Bdfsg-2/man.patch/
|

by Francois-Denis Gonthier <neumann@lostwebsite.net>.

|
|
Patch description rewritten for Guix.
|
|
|
|
This patch allows access to the man page with the 'erl -man' command
|
|
(Erlang manual pages are placed to /gnu/store/..erlang../share/man/ hierarchy
|
|
as other man pages.)
