# XPI_ID		- Extension id, might be in {12345-...} or dev@org format
# XPI_NUM		- Extension number, as in addons.cdn.mozilla.net URL
# XPI_FILES		- List of files in xpi archive. This is used to produce
#				  PLIST_FILES. XPI_FILES can be generated by xpi-gen, but be
#				  sure to put chrome.manifest in ${FILESDIR} before that if you
#				  need it.
# XPI_DISTNAME	- The name of distribution
#				  Default: ${PORTNAME}
# PORTNAME, PORTVERSION, DISTVERSIONSUFFIX, CATEGORIES, MAINTAINER, COMMENT
#				- These should all be set manually for port to be functional. See
#				  ${PORTSDIR}/Mk/bsd.port.mk for details.
# MASTER_SITES	- This should be set if port is unavailable at the default site.
#				  Default (defined below): ${MASTER_SITE_MOZILLA_ADDONS}
# MASTER_SITE_SUBDIR
#				- Default: extensions/${PORTNAME}
# LATEST_LINK	- Default: ${PKGBASE:S/_//g}
# XPI_LIBDIR	- Name of the directory to install extensions in.
#				  Default: ${PREFIX}/lib/xpi
# XPI_XPIDIR	- Name of the directory to install extension's files in.
#				  Default: ${XPI_LIBDIR}/${XPI_ID}
# USE_XPI		- If set, the port installs one or more xpi extensions.
#				  If this is set to a list of apps (wildcards possible) the
#				  extensions will be installed for them only.
# WITH_XPI		- A user-tunable variable, determines which apps should
#				  extension be made available for. Can be set to a list of
#				  apps, same as USE_XPI, and/or to "ext:app[,app,app,...]" tuples.
#				  ext should be a portname. If ext starts and ends with a slash
#				  (`/'), it is treated as an extended regular expression (see
#				  re_format(7)). Right of the colon should be a list of apps in
#				  the same format as USE_XPI, but comma- instead of whitespace-
#				  delimited. If no matching tuples for an extension are found,
#				  WITH_XPI is scanned for non tuple-records which are then treated
#				  as a USE_XPI list. If several tuples match, the last non-regexp
#				  one takes precedence, then the last regexp one.
#
# This Makefile is a beta-version of the new xpi infrastructure. It currently
# supports Gecko 1.8+ (Firefox 1.5+). Support for Gecko 1.7x (and Seamonkey 1.0)
# may be merged later from Thierry Thomas works.
#
# A new xpi will require a PORTNAME, PORTVERSION, DISTVERSIONSUFFIX and
# CATEGORIES. In case it is not published on the mozilla.org sites, MASTER_SITES
# can be redefined. XPI_* vars will also need to be defined manually, which helps
# keep the infrastructure simpler.
#
# Gecko 1.8 xpi engine tries to detect various compatibility issues all by itself.
# Thus, xpi's are installed into ${LOCALBASE}/lib/xpi/${XPI_ID} by default and
# links are made to all apps which have the engine (firefox, thunderbird, sunbird
# thunderbird3, seamonkey and flock at the moment). relink and relink-all targets
# can be invoked to refarm the links of a single extensions or all installed
# extensions accordingly.
#
# In case an xpi does not have chrome.manifest, it should be generated manually by
# a maintainer and placed in files, where it will be noticed. 
#
# xpi ports do not depend on their master applications. You can install an
# extension before the app and run relink when the app is present.
