ach is a Ruby helper for builder ACH files. In particular, it helps with field order and alignment, and adds padding lines to end of file.
This library has only been used in two production applications and for very limited purposes. Please test thoroughly before using in a production environment.
See ACH::Builder for a similar Perl library
You should consult a copy of the ACH Rules for details on individual fields. You can probably obtain a copy from your bank.
