This is a version of Epigram 1, recovered from the Wayback Machine and modified to build with current versions of GHC.
Current status: it builds using Stack, but the Elisp needs tweaking to find the build product.
Tested on GNU/Linux, contributions and testing are welcome from Mac OS and Windows users.
It would be convenient to get the interface to work with GNU Emacs
The current version here has not been thoroughly tested
It would be good to get it building with a few more systems in some kind of CI as well.
Run stack install to compile and install the Epigram binary, then run the epigram script in the project root to launch XEmacs and Epigram.
