# Note: These TODO may not be things I'm planning to fix. Some of them are just
# notes to be fixed by someone else who wants that functionality and warnings
# to those who are expecting that functionality. The HylaFAX+ and AvantFAX
# PKGBUILD have taken many days to get them functional on a modern OS.
# I can't spend a lot more time fixing things I don't use without help.

# TODO: Test receive fax functionality. I only send faxes.
# TODO: Verify timers work
# TODO: Check if Tesseract works
# TODO: Support for HylaFAX in extra (HylaFAX+ on AUR is supported)
# TODO: Less destructive remove or better cleanup.
# TODO: Even safer password storage (the current method is pretty safe)
# TODO: SendEmail or smtp-cli.pl support instead of sendmail
# TODO: We should stop using hard links. They won't update as the system updates.
# See avantfaxsetup.sh for more todo

# VERIFIED: Upon remove (and cleanup) 'avantfax' isn't found in /etc /var/spool/hylafax /usr/lib/fax
#  other than in the logs for faxes sent by AvantFAX.
# VERIFIED: AvantFAX integration for HylaFAX+ upgrades

# How to install:
# Setup these parameters
_opt_AUTO_START_HTTP=1 # 1 to automatically enable avantfax and restart apache, 0=manual
_opt_DEBUG_PHP=0       # 1 to show php debug messages, 0 for production
_opt_pagesize='letter' # a4, letter
_opt_phpver='php56'    # php56 for now, php when avantfax is php7 compatible

# With a non set up MySQL or a root password the install will fail.

# sudo vi /usr/bin/avantfaxsetup.sh.password

# Add mysql root password then finish install.

# sudo avantfaxsetup.sh install

# Check settings in /usr/share/webapps/avantfax/includes/local_config.php

# Cleanup: sudo rm -rf /usr/share/webapps/avantfax /root/avantfaxbackup
# Note: Removing the avantfax package is very destructive. It destroys all
# avantfax files and tables.
