+# argp-standalone
+
+This is a continuation of [Niels Möller](https://www.lysator.liu.se/~nisse/)'s
+work on an argp library for systems which don't provide one themselves (most
+non-GNU ones).
+
+After noticing issues with executables built against argp-standalone 1.3, I
+decided to fork it and continue the effort.
+
+This repository is the result of making a timeline with releases 1.0 to 1.3
+(obtained from [here](https://www.lysator.liu.se/~nisse/misc/)) of the original
+argp-standalone, copying files from glibc 2.33 and fixing them up for
+compatibility, and finally some general clean up. I commited many trivial
+changes from the glibc version in order to make updating easier.
+
+It is my expectation that this library will be useful to others. Feel free to
+open an issue or make a PR.
