# $(call GET_LATEST_VERSION, base url[, prefix, ext, filter, separator])
#  base url : required page returning list of versions
#               e.g https://ftp.gnu.org/gnu/libfoo
#  prefix   : segment before version
#               defaults to lastword of url with dash i.e. `libfoo-`
#  ext      : segment ending version - default `\.tar`
#  filter   : `grep -i` filter-out pattern - default alpha\|beta\|rc
#  separator: transform char to `.` - typically `_`
#
# test changes with:
# make check-get-latest-version
#
# and update tools/skeleton.py with usage notes
