Where this comes from
History was imported from https://sourceforge.net/projects/cpcrslib/
with
git clone https://git.code.sf.net/p/cpcrslib/code cpcrslib-code
cd cpcrslib-code/
Generated or binary files were spotted with:
find * -type f -not -iname "*.s" -not -iname "*.c" -not -iname "*.h" -not -iname "*.bat" -not -iname LICENSE -not -iname "*.txt" | egrep -o '\.[^\.]*$' | sort | uniq
.asm
.bin
.dsk
.exp
.lib

.rel
And history cleaned with:
git filter-branch -f --tree-filter 'find * -type f -not -iname "*.s" -not -iname "*.c" -not -iname "*.h" -not -iname "*.bat" -not -iname LICENSE -not -iname "*.txt" -print0 | xargs -0 rm -vf ' HEAD
