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,

parser is accurate, but a little on the lenient side. It is the

If separate `author` and `committer` commands are used in a `commit`
the timestamps may not match, as the system clock will be polled
Omitting the `from` command in the first commit of a new branch
will cause fast-import to create that commit with no ancestor. This
tends to be desired only for the initial commit of a project.
+If the frontend creates all files from scratch when making a new
+branch, a `merge` command may be used instead of `from` to start
+the commit with an empty tree.
Omitting the `from` command on existing branches is usually desired,
as the current commit on that branch is automatically assumed to
be the first ancestor of the new commit.

commit are permitted by fast-import, thereby establishing an n-way merge.
However Git's other tools never create commits with more than 15
additional ancestors (forming a 16-way merge). For this reason
it is suggested that frontends do not use more than 15 `merge`

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

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.
