+olm (olm and megolm cryptographic ratchets)
+
+An implementation of the Double Ratchet cryptographic ratchet described by
+https://whispersystems.org/docs/specifications/doubleratchet/, written in
+C and C++11 and exposed as a C API.
+
+The specification of the Olm ratchet can be found in olm.md.
+
+This library also includes an implementation of the Megolm cryptographic
+ratchet, as specified in megolm.md.
+
+Olm is designed to be easy port to different platforms and to be easy to
+write bindings for.
+
+It was originally implemented in C++, with a plain-C layer providing the
+public API. As development has progressed, it has become clear that C++
+gives little advantage, and new functionality is being added in C, with
+C++ parts being rewritten as the need arises.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
