# The DOWNLOAD_{GIT,SVN,BZR,HG,LOCALFILES} helpers are in charge of getting a
# working copy of the source repository for their corresponding SCM,
# checking out the requested version / commit / tag, and create an
# archive out of it. DOWNLOAD_SCP uses scp to obtain a remote file with
# ssh authentication. DOWNLOAD_WGET is the normal wget-based download
# mechanism.
#
# The SOURCE_CHECK_{GIT,SVN,BZR,HG,WGET,LOCALFILES,SCP} helpers are in charge of
# simply checking that the source is available for download. This can be used
# to make sure one will be able to get all the sources needed for
# one's build configuration.
#
# The SHOW_EXTERNAL_DEPS_{GIT,SVN,BZR,HG,WGET,LOCALFILES,SCP} helpers simply
# output to the console the names of the files that will be downloaded, or path
# and revision of the source repositories, producing a list of all the
# "external dependencies" of a given build configuration.
