An incomplete and unstable engine for typesetting mathematical formulas with bitmap fonts and bitmap outputs. The quality is, needless to say, far coarser than other tools such as TeX; it is nevertheless much smaller than those tools in size. There's only one bitmap font with a very limited character set, after all!
This is a complete rewrite of SLZEE 1, which was written in Ruby and a mess, in C99, and now it seems even messier.
To build on Windows or *nix systems:
wget -O lodepng.c https://raw.githubusercontent.com/lvandeve/lodepng/master/lodepng.cpp
cc slzee2.c lodepng.c -o slzeeSLZEE 2 reads the equation to be typeset from the standard input only.
