Anagallis, a program for parsimony analysis of character hierarchies. Version 1.03, 8 September 2020. Program and documentation (current version).
Pdf of a dump of the built-in documentation of anagallis version 1.03,
including a discussion of the theory behind the program, of the high level structure of its main optimization algorithm, and of the scope and limits of that algorithm.
A gzipped tarfile that contains Linux and macOS executables and several files to get started with the program is available here.
Basic instructions, including how to get started once the gzipped tarfile is downloaded, can be found here.
