+
+ Uploads a Debian source package to a cowbuilder host and builds it,
+ optionally also signing and uploading the result to an incoming queue.
+ The following options are supported:
+
+ --arch="arch" Specify the Debian architecture(s) to build for.
+ --dist="dist" Specify the Debian distribution(s) to build for.
+ --buildd="host" Specify the remote host to build on.
+ --buildd-user="name" Specify the remote user to build as.
+ --create Create the remote cowbuilder root if necessary.
+ --return[="path"] Copy results of the build to 'path'. If path is
+ not specified, return them to the current directory.
+ --no-return Do not copy results of the build to RETURN_DIR
+ (overriding a path set for it in the config files).
+ --sign="keyid" Specify the key to sign packages with.
+ --upload="queue" Specify the dput queue to upload signed packages to.
+
+ The current default configuration is:
+
+ BUILDD_HOST = $BUILDD_HOST
+ BUILDD_USER = $BUILDD_USER
+ BUILDD_ARCH = $BUILDD_ARCH
+ BUILDD_DIST = $BUILDD_DIST
+ RETURN_DIR = $RETURN_DIR
+ SIGN_KEYID = $SIGN_KEYID
+ UPLOAD_QUEUE = $UPLOAD_QUEUE
+
+ The expected remote paths are:
+
+ INCOMING_DIR = $INCOMING_DIR
+ PBUILDER_BASE = ${PBUILDER_BASE:-/}
+
+$(get_archdist_vars display)
+$(display_override_vars)
+
+ The cowbuilder image must have already been created on the build host
+ and the expected remote paths must already exist if the --create option
+ is not passed. You must have ssh access to the build host as BUILDD_USER
+ if that is set, else as the user executing cowpoke or a user specified
+ in your ssh config for '$BUILDD_HOST'.
+ That user must be able to execute cowbuilder as root using '$BUILDD_ROOTCMD'.

+ # hook using options from git-config, will preserve any quoting that was used in
+ # the .gitconfig file, which is natural for anyone to want to use in a construct
+ # like: options = --dpkg-opts='-uc -us -j6'. People are going to cringe if we
+ # tell them they must not use quotes there no matter how much it may 'make sense'
+ # if you know too much about the internals. And it will only get worse when we
+ # then tell them they must quote it like that if they type it directly in their
+ # shell ...
+ #
+ # So we do the only thing that seems sensible, and try to Deal With It here.
+ # If the outermost characters are paired quotes, we manually strip them off.
+ # We don't want to let the shell do quote removal, since that might change a
+ # part of this which we don't want modified.
+ # We collect however many sets of those we are passed in an array, which we'll
+ # then combine back into a single argument at the final point of use.
+ #
+ # Which _should_ DTRT for anyone who isn't trying to blow this up deliberately
+ # and maybe will still do it for them too in spite of their efforts. But unless
+ # someone finds a sensible case this fails on, I'm not going to cry over people
