# This file for ports which depend on emacs family.
# Define EMACS_PORT_NAME variable before bsd.port.[pre.]mk
# and it will automatically include this file.
#
# This file exports the following common variables:
#
# EMACS_NAME:
#		emacsen's command-line basename.
#		ex.) "emacs" when emacsen is a emacs-20.6.
#
# EMACS_VER:
#		emacsen's version.
#		ex.) "20.6" when emacsen is a emacs-20.6.
#
# EMACS_MAJOR_VER:
#		emacsen's major version.
#		ex.) "20" when emacsen is a emacs-20.6.
#
# EMACS_LIBDIR:
#		emacsen's library directory name without ${PREFIX}.
#		ex.) "share/emacs" when emacsen is a emacs-20.6.
#
# EMACS_LIBDIR_WITH_VER:
#		emacsen's version specific library directory name 
#		without ${PREFIX}.
#		ex.) "share/emacs/20.6" when emacsen is a emacs-20.6.
#
# EMACS_CMD:
#		emacsen's command-line filename. (full path)
#		ex.) "/usr/local/bin/emacs-20.6" when emacsen is a 
#		     emacs-20.6 and ${PREFIX} is "/usr/local".
#
# EMACS_SITE_LISPDIR:
#		emacsen's site-lisp directory name without ${PREFIX}.
#		ex.) "share/emacs/site-lisp" when emacsen is a emacs-20.6.
#
# EMACS_VERSION_SITE_LISPDIR:
#		emacsen's version specific site-lisp directory name
#		without	${PREFIX}.
#		ex.) "share/emacs/20.6/site-lisp" when emacsen is a
#		emacs-20.6.
#
# EMACS_NO_BUILD_DEPENDS:
#		If set "YES" to this variable, port does not 
#		build-depend on EMACS_PORT_NAME's emacsen.
#
# EMACS_NO_RUN_DEPENDS:
#		If set "YES" to this variable, port does not 
#		run-depend on EMACS_PORT_NAME's emacsen.
