Reads tokenized GFA BASIC version 3.x source files (.GFA) and converts them to human readable ASCII listings (.LST).

This is a fixed version of the original ONS tool available at: http://titan.plasma.xg8.de:8080/~rtc/

It can be used along with git to get text diffs on GFA files (but not merges):

# make sure you have gfalist in your $PATH

$ git diff
diff --git a/test.gfa b/test.gfa
index 9dfbbd6..b8612d8 100644
Binary files a/test.gfa and b/test.gfa differ
$ git config --local diff.gfa.textconv 'gfalist -c'
$ echo '*.gfa diff=gfa' >> .gitattributes
$ git diff
diff --git a/test.gfa b/test.gfa
index 9dfbbd6..b8612d8 100644
--- a/test.gfa
+++ b/test.gfa
