+This application aims to replicate a small GNU Coding Standards
+configure script, taylored at projects in GNU Taler. We hope it
+can be of use outside of GNU Taler, hence it is dedicated to the
+public domain ('0BSD').
+It takes a couple of arguments on the commandline equivalent to
+configure by autotools, in addition some environment variables
+xan take precedence over the switches. In the absence of switches,
+/usr/local is assumed as the PREFIX.
+When all data from tests are gathered, it generates a config.mk
+Makefile fragement, which is the processed by a Makefile (usually) in
+GNU Make format.
