[GNC] A repository for user-contributed files

[Frank H. Ellenberger]

I found it on the still unlinked (=unpublished?) page
https://wiki.gnucash.org/wiki/Documentation_Overview.

As I am not satisfied by all the unmaintable redundancies, suboptimal
structures, … I outlined some relations, constrains, … But then I got
distracted.

Do you think parts are usable and deserve a more prominent place?

Regards
Frank
