content to the top level.

-BitBake 'Fetch' git implementation
-
-git fetcher support the SRC_URI with format of:
-SRC_URI = "git://some.host/somepath;OptionA=xxx;OptionB=xxx;..."
-
-Supported SRC_URI options are:
-
-- branch
-   The git branch to retrieve from. The default is "master"
-
-   This option also supports multiple branch fetching, with branches
-   separated by commas.  In multiple branches case, the name option
-   must have the same number of names to match the branches, which is
-   used to specify the SRC_REV for the branch
-   e.g:
-   SRC_URI="git://some.host/somepath;branch=branchX,branchY;name=nameX,nameY"
-   SRCREV_nameX = "xxxxxxxxxxxxxxxxxxxx"
-   SRCREV_nameY = "YYYYYYYYYYYYYYYYYYYY"
-
-- tag
-    The git tag to retrieve. The default is "master"
-
-- protocol
-   The method to use to access the repository. Common options are "git",
-   "http", "https", "file", "ssh" and "rsync". The default is "git".
-
-- rebaseable
-   rebaseable indicates that the upstream git repo may rebase in the future,
-   and current revision may disappear from upstream repo. This option will
-   remind fetcher to preserve local cache carefully for future use.
-   The default value is "0", set rebaseable=1 for rebaseable git repo.
-
-- nocheckout
-   Don't checkout source code when unpacking. set this option for the recipe
-   who has its own routine to checkout code.
-   The default is "0", set nocheckout=1 if needed.
-
-- bareclone
-   Create a bare clone of the source code and don't checkout the source code
-   when unpacking. Set this option for the recipe who has its own routine to
-   checkout code and tracking branch requirements.
-   The default is "0", set bareclone=1 if needed.
-
-- nobranch
-   Don't check the SHA validation for branch. set this option for the recipe
-   referring to commit which is valid in tag instead of branch.
-   The default is "0", set nobranch=1 if needed.
-
-- usehead
-   For local git:// urls to use the current branch HEAD as the revision for use with
-   AUTOREV. Implies nobranch.
