 # Parsee - the jealous XMPP<=>Matrix bridge

+## TODOS before 1.0 rolls around
+- Add [libomemo](https://github.com/gkdr/libomemo) or something as an optional dependency. 
     - It depends on more stuff anyways, and I don't want to weigh down the 
     dependency list of Parsee for that.
     - Matrix's libolm is deprecated. They replaced it with a Rust version that 
     pulls in *way too many* dependencies, and that lacks a C binding. We may 
     put in the work of either forking off libolm or making a binding to KappaChat.

+        willing to help out, but IDK. In any case, this will at best be an 
+        extension packagers may integrate properly.
 - Get rid of the '?'-syntax and use another invalid Matrix char/valid XMPP char 
 ('$'?) for escaped?
 - PROPER FUCKING AVATARS
