As part of my glacially-slow project of creating source code repositories on GitHub for all software available from Fourmilab, the master source code for Anagram Finder may now be cloned or downloaded from the repository:
https://github.com/Fourmilab/anagram
The initial commit to this repository corresponds to version 1.5 of Anagram Finder, released on 2019-08-08. Subsequent updates (if any should be forthcoming) will be tracked through the GitHub change control mechanism. The repository includes the C++ and PDF source and documentation files generated from the Literate Programming CWEB master files so those who clone the repository need not re-generate them in order to build the program.
