# Makefile for the Hunspell dictionary of Computer Jargon
#
# Input is a simple text file with one word per line
#
# The vocabulary and dictionary files use the following format:
# - line 1: number of entries
# - remaining lines: one entry per line
#
# A sorted file is created by using the following steps:
# - sort all enries in reverse order
# - use awk to add a final line with the number of entries
# - reverse the final file; use 'tac' (Linux) or 'tail -r' (MacOS)
