# Orginally based on a Debian Squeeze package


# Cleaned up the place (unneeded variables, 3-space tabs, hardcoded ZoneMinder-$pkgver references instead of $pkgname-$pkgver ones, wrong upstream URL, wrong license, missing conflict with 'zoneminder-git', etc).
#
# Removed sources for redundant patches as they aren't relevant anymore (source files have been altered and/or already include the patch changes).
#
# Replaced git clone for CakePHP and Crud sources with published precompiled packages, as follows:
# - CakePHP-Enum-Behaviour is pulled from the ZoneMinder repo, because a change is needed that has not yet been merged upstream.
# - Crud is pulled from its official repo, since Pull Request #582 has been merged as required by the ZoneMinder devs.
#
# Adjusted dependencies using as reference the control files for Ubuntu & Debian .deb packages provided by upstream, and also via trial and error (e.g. I couldn't find any mention of perl-crypt-ssleay in any of the official documents, but apparently it's needed otherwise zmupdate.pl complains that LWP::Protocol::https is not installed)
#
# Changed the folder structure a bit (so it would be a good idea to not blindly upgrade an older installation with this PKGBUILD, unless you want to risk being left with redundant and untracked by pacman folders and/or files).
#
# Replaced Apache with Nginx.
#
# ZoneMinder now runs at localhost:8095, instead of localhost/zm (this can be changed by editing the provided Nginx conf file).
#
# Completely overhauled the setup procedure:
# - The install script now takes into account the instructions in the INSTALL file provided by upstream.
# - All extra files (systemd service, systemd tmpfile, server configuration) have been merged into the install script.
# - ZoneMinder now works "out of the box": the database is automatically created, Nginx is automatically configured, PHP-FPM as well.
