Demo superimpose/ghost reimplementation of demsuperimpose and demogobbler for GoldSrc.
Beside that functionality, this thing can also write and parse demo.It will be moving to a different repository dem
demosuperimpose-goldsrc will be purely for implementation of demo tools.
I am not sure. Beside the obvious uplift of compiled executable, coldemoplayer pretty much has already finished all the hard work beside a writer. Bandwagon I think.
Check for files in src/demo_doer/ to see how to write your own functionality.
Mostly based of these.
