# This is an improved package for flite version 1 (flite1).
#
# flite version 1 is an old software from 2009. Since there, many issues
# have been discovered, including the security issue CVE-2014-0027. There
# are patches out there that addresses many of the discovered issues,
# and also adds some fixes and enhancements.
#
# Another notable issue that is also worth to be mentioned is a linking
# problem. This linking issue was exposed by upstream ffmpeg git commit
# 6dfcbd8. Without the propper patch, ffmpeg versions 3.5 and later will
# not compile, failing to detect libflite.
