Setting up werc on Plebeian
To install werc on the Plebeian GNU/Stallman Universal Operating System: (or any Linux/MODERN UNIX thing, pretty much)
hg clone http://hg.cat-v.org/werc/
Replace the awk urlencode/urldecode with the 9front one from 9base (in /usr/local/plan9/bin/urlencode). This is not included in the 9base in Debian or the suckless one; you need the fork. This is both to make posting with blagh and dirdir faster (not terribly slow) and to keep blagh and dirdir from truncating longer posts, which was an issue with this blog.
Optionally, replace the markdown.pl perl script with Discount, which supports curly quotes and other fancy stuff, is written on C, and will apparently compile on Plan 9.
This blog would probably run on 9front or 9atom or something if money was no object.
This extremely comprehensive guide may or may not be expanded upon even further at some point in the future.
