1. Wiki points to broken link, so I was unable to download pylmouth source. I downloaded it from github and in next step type git checkout 0.8.8
2. convert program don't worked for me - probably TCE contains newer version, so I use other theme
3. Tiny core contains never GCC, so in src/libply/ply-key-file.c I must change each %a (in format string) to %m .
