# ``COMPONENT``

# The name that will appear in the GUI installers for this component
#
# ``SUMMARY``
# A short one line summary of the package
#
# ``DESCRIPTION``
# A longer description of the package
#
# ``GROUP``
# Used to combine packages in GUI installers. Ignored in DEB and RPM installers
#
# ``DEB_PACKAGE_NAME``
# Name of the package for the DEB installers. This is the first component of the
# file name.
#
# ``DEB_PROVIDES``
# The virtual packages provided by the deb package. This is a higher level name
# of the file that can be used across version numbers. also includes the version
# information about the package
#
# ``DEB_REPLACES``
# The packages and virtual packages this will replace. Used if there is a package
# that is installed as part of the base debian installation
#
# ``REQUIRES``
# The components required for the GUI installers
#
# ``OPTIONAL``
# Optional packages that this component can use.
#
# ``INSTALL_TYPE``
# A group of components that will be selected in GUI installers from a drop down
#
# ``DEB_REQUIRES``
# Set of packages required by the debian package. This is slighly different from
# REQUIRES because it also takes into account external dependencies that can be
# installed by apt
#
# ``DEB_OPTIONAL``
# Same as OPTIONAL but for debian packages
#
# ``DEB_RECOMMENDS``
# Packages that should be installed but are not required. These packages will
# be installed by default but if removed will not also delete this package
#
# ``HIDDEN``
# If set, the package will not appear in the GUI installers like NSIS. Usually
# components that install dependencies
