# Provide support for Common Lisp ports.
#
# Feature:	cl
# Usage:	USES=cl
# Valid ARGS:	none
#
# Variables, which may be set by ports:
# ASDF_MODULES   - List of ASDF modules to build when FASL_TARGET is set (defaults to PORTNAME)
# FASL_TARGET    - Build fasl variant of port (one of ccl, clisp, or sbcl)
# USE_ASDF       - Depend on devel/cl-asdf
# USE_ASDF_FASL  - Depend on devel/cl-asdf-<FASL_TARGET>
# USE_CCL        - Depend on lang/ccl; implied when FASL_TARGET=ccl
# USE_CLISP      - Depend on lang/clisp; implied when FASL_TARGET=clisp
# USE_SBCL       - Depend on lang/sbcl; implied when FASL_TARGET=SBCL
#
# Variables to be read by ports:
# ASDF_PATHNAME  - Path to CL source
# ASDF_REGISTRY  - Path to CL registry containing asd files
# CCL            - Path to the Clozure Common Lisp compiler
# CLISP          - Path to the GNU Common Lisp compiler
# CL_LIBDIR_REL  - CL library directory relative to LOCALBASE or PREFIX
# DOCSDIR        - DOCSDIR accounting for cl- PKGNAMEPREFIX
# EXAMPLESDIR    - EXAMPLESDIR accounting for cl- PKGNAMEPREFIX
# FASL_DIR_REL   - Relative path to compiled fasl files; depends on FASL_TARGET
# FASL_PATHNAME	 - Path to CL fasl
# LISP_EXTRA_ARG - Extra arguments used when building fasl
# SBCL           - Path to the Steel Bank Common Lisp compiler
