rename project: gotmarc -> smarc

add maintainer target to generate an html version of the man pages

typo

add a configure script and rework the make infrastructure don't depend on bsd.prog.mk & co; first step to make it portable.

move the archive logic from the makefile to the gotmarc script the makefile now is only there to build/install the got assets

build a cache of hashes for each thread The idea is to use this cache to spot changed threads and re-export all the mail of the threads that changed. This will allow to add thread navigation hints on each exported mail and have them up-to-date. This makes the "skip if already exported" logic in mexp redundant and incomplete. pe will decide whether to export or not, and mexp blindly do the work.

do a round of optipng on the images to save some bytes

bundle the images and drop the hard dependency on imagemagick

drop trailing slash

needless trailing slash

less chatty

change MDIR and OUTDIR defaults

don't export the mbox this wasn't a good idea as the mbox contains sensitive data (IP addresses, hostnames and whatnot). Not good to publish on the web. Reminded by Stefan

simplify the makefile move the logic of the export to gotmarc, where it's easier to set up the correct env. While here improve the makefile to generate the images and the copy the style only if needed.

parallelize exporting mexp is the slowest part of the pipeline. Try to speed it up by paralellizing it. this adds a `pe' scripts that sits in front on N mexp childs and dispatch threads to them, while still outputting the unchanged lines for mkindex. Unscientific testing has shown that this effectively reduces the time for a full export, even if not linearly. (4 jobs cut the time in half, 8 jobs was just barely faster)
