It kinda pisses me off that you complain about the excessive detail of
git documentation, and then ask others to tell you about the details
you could read in the documentation.

Specifically, according to the help, git-gc removes garbage (in the
usual sense of a tracing collector) and "compresses" (ie, packs) loose
objects using delta compression (and then the result is deflated as
with loose objects, I believe).  It will repack the packs into *one*
pack (presumably with better delta compression) if the number of packs
is greater than the value of gc.autopacklimit (in .git/config;
default: 50).
