erlang-syntax-tools 1:22.1.8+dfsg-1 (armhf binary) in ubuntu focal

 Syntax_Tools contains modules for handling abstract Erlang syntax
 trees in a way that is compatible with the "parse trees" of the
 STDLIB module erl_parse, together with utilities for reading source
 files in unusual ways and pretty-printing syntax trees. Also it
 includes a module merger and renamer called Igor, as well as an
 automatic code-cleaner.
