# These options are target language independent, and used by
# Registry.apiGen() and by base OutputGenerator objects.
#
# Members
# conventions - may be mandatory for some generators:
# an object that implements ConventionsBase
# filename - basename of file to generate, or None to write to stdout.
# directory - directory in which to generate filename
# apiname - string matching <api> 'apiname' attribute, e.g. 'gl'.
# profile - string specifying API profile , e.g. 'core', or None.
# versions - regex matching API versions to process interfaces for.
# Normally '.*' or '[0-9]\.[0-9]' to match all defined versions.
# emitversions - regex matching API versions to actually emit
# interfaces for (though all requested versions are considered
# when deciding which interfaces to generate). For GL 4.3 glext.h,
# this might be '1\.[2-5]|[2-4]\.[0-9]'.
# defaultExtensions - If not None, a string which must in its
# entirety match the pattern in the "supported" attribute of
# the <extension>. Defaults to None. Usually the same as apiname.
# addExtensions - regex matching names of additional extensions
# to include. Defaults to None.
# removeExtensions - regex matching names of extensions to
# remove (after defaultExtensions and addExtensions). Defaults
# to None.
# emitExtensions - regex matching names of extensions to actually emit
# interfaces for (though all requested versions are considered when
# deciding which interfaces to generate).
# sortProcedure - takes a list of FeatureInfo objects and sorts
# them in place to a preferred order in the generated output.
# Default is core API versions, ARB/KHR/OES extensions, all
# other extensions, alphabetically within each group.
# The regex patterns can be None or empty, in which case they match
