bootstrap

#!/bin/sh
# bootstrap — generate ./configure and the Makefile.in files (GNU Autotools).
#
# Usage:
#   ./bootstrap          generate configure; then: ./configure && make
#   ./bootstrap --dev    also create .venv with the development tools, for
#                        working on codebud itself
#
# Needs GNU autoconf (>= 2.69) and automake (>= 1.16); building the manual
# needs GNU texinfo. Release tarballs ship a ready-made configure, so this is
# only needed in a git checkout.
