# This script tangles all the org-mode files in the src directory of QMCkl.
# It needs to be run from in the src directory. It uses the config_tangle.el
# Emacs configuration file, which contains information required to compute the
# current file names using for example ~(eval c)~ to get the name of the
# produced C file. The org-mode file is not tangled if the last modification
# date of the org file is older than one of the tangled files.
# The =missing= script is used to check if emacs is present on the system.
