# Rosegarden Project file packager
# Copyright 2005-2008 Chris Cannam and Fervent Software Ltd.
# Distributed under the GNU General Public License.
#
# This program converts between Rosegarden (.rg) files and Rosegarden
# Project (.rgp) files.
#
# A Rosegarden file (.rg) is a single file (in gzipped XML format)
# that defines a Rosegarden composition in terms of events, segments,
# programs, plugin data, references to audio files, and so on. Some
# of these types of information depend on the presence of external
# files such as the audio files or plugin preset data, without which
# the file cannot be used.
#
# A Rosegarden Project (.rgp) file is a bundle of files, including the
# Rosegarden file itself, as well as any audio file or other external
# data it requires, in compressed form. A Rosegarden Project file is
# intended to be portable and self-contained, but the Rosegarden
# program itself does not (at the time of writing) understand these
# files directly.
#
# This program can take a Rosegarden file, examine it to find out
# which other data files it uses, and pack it to create the
# corresponding Rosegarden Project file. Conversely, it can also take
# a Rosegarden Project file and unpack it as a project directory for
# use with Rosegarden.
# TODO:
# - quiet
# - versioning
# - graceful recovery from running out of disk space
# - mucho tidying
