#!/usr/bin/perl
# Output a version.c file that includes information about the current build
# Normally a couple of lines of bash would be enough (see openpcd project, original firmware by Harald Welte and Milosch Meriac)
# but this will, at least in theory, also work on Windows with our current compile environment.
