-f <file>::
Read patterns from <file>, one per line.
+-e::
+ The next parameter is the pattern. This option has to be

`<tree>...`::
Search blobs in the trees for specified patterns.
--skip::
Restart the rebasing process by skipping the current patch.
- This does not work with the --merge option.
--merge::
Use merging strategies to rebase. When the recursive (default) merge
not autocommit, to give the user a chance to inspect and
further tweak the merge result before committing.
+--squash::
+ Produce the working tree and index state as if a real
+ merge happened, but do not actually make a commit or
+ move the `HEAD`, nor record `$GIT_DIR/MERGE_HEAD` to
+ cause the next `git commit` command to create a merge
+ commit. This allows you to create a single commit on

+ merging another branch (or more in case of an octopus).
