#
# Build history:
#
# 1.0 - Initial release.
# 1.1 - Removed a bashism (==) to become ash-compatible.

# 20220225 bkw: I just have to ask. Why care about being ash compatible?
# When are you ever going to run this script with ash?

# 20220222 bkw: Modified by SlackBuilds.org:
# - fix bad github filename.
# - do not install the docs with execute permission.
# - reword README stuff about qt (it's not a "Qt GUI", it's a library)
#   and mention qt4 as an optional dep.

# Note: python bindings are not built, partly because it's hardcoded
# for python 3.5, and (if overridden with YAF_PY_VERSION=3.9) because
# it fails to build. Maybe someone will have time to fix this someday?
