DESCRIPTION
-----------
This program is usually not what the end user wants to run directly.
Most end users want to use one of the existing frontend programs,
which parses a specific type of foreign source and feeds the contents

fast-import reads a mixed command/data stream from standard input and
writes one or more packfiles directly into the current repository.

The fast-import backend itself can import into an empty repository (one that

update an existing populated repository. Whether or not incremental
imports are supported from a particular foreign source depends on
the frontend program in use.
This information may be useful after importing projects
whose total object set exceeds the 4 GiB packfile limit,
as these commits can be used as edge points during calls

commit(s) which are supplying file revisions to the fixup branch.

~~~~~~~~~~~~~~~~~~~~~~~~~
If you are repacking very old imported data (e.g. older than the
last year), consider expending some extra CPU time and supplying
-\--window=50 (or higher) when you run linkgit:git-repack[1].
+\--window=50 (or higher) when you run 'git-repack'.
This will take longer, but will also produce a smaller packfile.
You only need to expend the effort once, and everyone using your
project will benefit from the smaller repository.
