Currently, various warnings are given when RepnDecomp is loaded without IO:

However, the package nevertheless loads successfully, and the test files run properly, without IO being loaded.

I'd suggest doing something to get rid of these syntax warnings. I'll make a pull request with a hack; there might be better options.

Anything specific to fix in RepnDecomp? Please let me know, and @ me in the future on this package (it's not abandoned by me, just somehow no notifications per email arrived)

[wilfwilson]

The only thing required is merging #24 and making a release.

Will @ you in the future
