# ============================================================================

# ============================================================================
#
# SYNOPSIS
#
# AX_SPEC_PACKAGE_AND_VERSION ([specfile])
# AX_SPEC_PACKAGE_NAME ([shellvar],[defaultvalue])
# AX_SPEC_PACKAGE_VERSION ([shellvar],[defaultvalue])
# AX_SPEC_PACKAGE_SUMMARY ([shellvar],[defaultvalue])
# AX_SPEC_PACKAGE_LICENSE ([shellvar],[defaultvalue])
# AX_SPEC_PACKAGE_CATEGORY ([shellvar],[defaultvalue])
# AX_SPEC_PACKAGE_ICON ([shellvar],[defaultvalue])
# AX_SPEC_DEFAULTS([specfile])
#
# DESCRIPTION
#
# set PACKAGE from the given specfile - default to basename of the
# rpmspecfile if no "name:" could be found in the spec file.
#
# set VERSION from the given specfile - default to a date-derived value if
# no "version:" could be found in the spec file.
#
# this macro builds on top of AX_SPEC_FILE / AX_SPEC_EXTRACT
#
# more specific: if not "name:" or "%define name" was found in the
# myproject.spec file then the PACKAGE var is set to the basename
# "myproject". When no spec file was present then it will usually default
# to "TODO".
#
# The version spec looks for "version:" or "%define version" in the spec
# file. When no such value was seen or no spec file had been present then
# the value is set to `date +0.%y.%W%w`.
#
# the version value itself is sanitized somewhat with making it to always
# carry at least three digits (1.2.3) and cleansing superfluous "0" chars
# around from generating numbers elsewhere.
#
# additional macros are provided that extract a specific value from the
# spec file, among these:
#
# set PACKAGE_SUMMARY from the given specfile - default to package and try
# to detect a type suffix if "summary:" was not in the spec file
#
# set PACKAGE_LICENSE from the given specfile - if no "license:" tag was
# given in the spec file then various COPYING files are grepped to have a
# guess and the final fallback will be GNU GPL (or GNU LGPL).
#
# set PACKAGE_ICON from the given specfile - if no "icon:" tag was given
# in the spec file then we default to $PACKAGE-icon.png
#
# the final AX_SPEC_INIT(specfile) will initialize all variables to its
# defaults according to the spec file given.
