          Writing C software without the standard library
                           Linux Edition
###################################################################
There are many tutorials on the web that explain how to build a
simple hello world in C without the libc on AMD64, but most of them
stop there.

I will provide a more complete explanation that will allow you to
build yourself a little framework to write more complex programs.

# e621 downloader. maintains a mirror of e621 (just DB export+images, not the HTML)
# suggested use is to run this from crontab once per day.
# this maintains an infinite number of database snapshots and also keeps deleted images forever (in a separate directory) because I'm a packrat. feel free to modify to delete old stuff.
