We produce some simple "Get" messages that aren't super clear as to what they're doing, especially for people not familiar with repo. Rephrase these to explicitly state the thing we're doing so it's clear why we're downloading a particular source.

|
|
The '%prog' command is run once to install and initialize repo.
|
|
The latest repo source code and manifest collection is downloaded
|
|
from the server and is installed in the .repo/ directory in the
|
|
current working directory.
|
|
|
|
The optional -b argument can be used to select the manifest branch
|
|
to checkout and use. If no branch is specified, master is assumed.
|
|
|
|
The optional -m argument can be used to specify an alternate manifest
|
|
to be used. If no manifest is specified, the manifest default.xml
|
|
will be used.
|
|
|
|
The --reference option can be used to point to a directory that
|
|
has the content of a --mirror sync. This will make the working
|
|
directory use as much data as possible from the local reference
|
|
directory when fetching from the server. This will make the sync
|
|
go a lot faster by reducing data traffic on the network.
|
|
|
|
The --dissociate option can be used to borrow the objects from
|
|
the directory specified with the --reference option only to reduce
|
|
network transfer, and stop borrowing from them after a first clone
|
|
is made by making necessary local copies of borrowed objects.
|
|
|
|
The --no-clone-bundle option disables any attempt to use
|
|
$URL/clone.bundle to bootstrap a new Git repository from a
|
|
resumeable bundle file on a content delivery network. This
|
|
may be necessary if there are problems with the local Python
|
|
HTTP client or proxy configuration, but the Git binary works.
|
|
|
|
# Switching Manifest Branches
|
|
|
|
To switch to another manifest branch, `repo init -b otherbranch`
|
|
may be used in an existing client. However, as this only updates the
|
|
manifest, a subsequent `repo sync` (or `repo sync -d`) is necessary
|
|
to update the working directory files.
