Hi there,
May be I missed something, I fail to clone the ATS1 repository which seems to not be at the URL indicated at some places, like in the ATS2 wiki on GitHub. This URL seems not be the good one:
https://ats-lang.svn.sourceforge.net/svnroot/ats-lang/trunk . I remember this URL used to be OK in the paste.
Since ATS2 is written in ATS1 and ATS2 is there for some time again (and looks good enough :-p ), ATS1 may still be needed if one want to try to fix or test something in the ATS2 complier.
Or may be I missed ATS2 is now written in ATS2? (both looks so similar …)
