This documentation is part of the application, it's referenced in the
NextCloud's web interface. Moreover NextCloud has some files consistency
check that doesn't like when the documentation is missing.
It's totally wrong to install pkg's files into /var/lib and make them
writable by webserver! Moreover when Nextcloud supports multiple
app paths.
So we use two apps locations:
* /usr/share/webapps/nextcloud/apps - for apps installed by apk,
* /var/lib/nextcloud/apps - for apps installed from AppStore.
BTW Fedora uses the same approach.
There two main reasons for this change:
* Active support of PHP 5.x ended on January 2017, security support will
end on December 2018. Packages in the main repository should be
supported for at least 2 years, this means until first quarter of 2019
for the upcoming v3.6.
* php7 and its extensions are currently in the community repository, so
we can't use single abuild for both php5-* and php7-* packages (as we
do for Python and Lua packages).
This change was suggested by @vakartel, approved by @ncopa, @kaniini, and
@jirutka.
