Crypto
======

MD5, ChaCha and SHA-3 are built into the interpreter.  Blowfish is a
plugin, loaded on demand:

	(load-option 'blowfish)

All of these are upstream's own implementations; no external crypto
library is used, at build time or at run time.

Plugins
=======

Blowfish, GDBM, PostgreSQL and X11 support are built as plugins and
dynamically loaded by load-option rather than linked into the
interpreter.

See debian/NOTES.md in the source package for build and porting notes.
