reading .roi files (outside ImageJ)

I'm collaborating on a project.  My collaborator has created many, many .roi files (each one containing a single PolygonRoi).
I can drag&drop the .roi file on FIJI, and use File->Save As->XY Coordinates to get a .txt file that I can read in a non-ImageJ
Java program.

But, this will be tedious.  Is there a simple way to automate this?

a) first choice: is there a description of the .roi file format?  Given sufficient documentation, I'm comfortable
writing code to read the .roi file directly
b) second choid: a SIMPLE macro that will read all of the .roi files in a directory and create .txt files containing the XY coordinates.

I'm a skilled Java progammer - but very much a novice at ImageJ macros.  I expect that my major stumbling block would be
writing a macro to read in all of the .roi files, one at a time.  I think I could save to .txt files just fine, once
I have the .roi file read in.  [ I know this is trivial for many of you - have pity on me. ]

For scale - I anticipate approximately 60 .roi files.  Not out of the question to simply do one at a time, by hand - but
(if it's simple) I'd rather let a macro do the iteration.
