Thanks to Simon Marlow for the explanations.
By the way, I somehow lost the way to the Postscript file of the GHC User Guide, how does one get it?
With .ps, I sometimes print the Manual to the paper, to book. Say, print the pages 1 -- 300. I do not know how to do this with .html. I can convert some small part to .ps when viewing .html. But it is desirable to be able to convert it all to one .ps file. I am sorry for the ignorance, but does .html replace fully .ps ? On DoCon test for GHC --------------------- is suggestion to use DoCon for the automatic GHC test. For many years, almost any new GHC version has a bug which is displayed by 1) `making' DoCon ported from the last GHC version, 2) running T_.test. Simon Marlow wrote that the reason for not doing this is that it is a lot of code for the nightly builds. But DoCon source + manual.ps make a file docon-xxx.zip of about 800 K byte, 5 times smaller than ghc-src. It builds in a couple of minutes, it is 20 times faster than ghc builds from source. On last reliable GHC version ---------------------------- For any occasion: it is good to always keep available on public the latest reliable GHC version. For example, the DoCon program failed (so far) with ghc-6.0.1, due to the gc bug in ghc. And the DoCon Installing guide says: "it was tested for ghc-5.02.2 ...". At least, DoCon user should be able to download and install this ghc-5.02.2 (in this particular case, I suspect, 5.04 fits). With kind regards, ----------------- Serge Mechveliani mechvel@botik.ru
