Hello, Mercury users. I have a very basic question: How exactly do I build the stuff from the mercury-extras package (tarball actually)?The README says to do `mmake depend' to the root directory, then go to each subdir and do `mmake' and `mmake install'. However, `mmake depend' fails, because lex has no target 'depend'. When I go directly to the subdirs, some of them do not have any targets at all: for example base64 contains only one file and the CVS subfolder. So, I'd appreciate a little bit more detailed instruction on building the extras. Perhaps the process is different for each subfolder? Or I am no reading the right place? If so, could you point me in the correct direction? Also, another partly related question: while building I glimpsed something like libmer_www, does that mean Mercury has some sort of web framework? Thanks for your time.
