 #
 # bsd.licenses.mk - License auditing framework.
 #
 # Created by: Alejandro Pulver <alepulver@FreeBSD.org>
 #
 # Please view me with 4 column tabs!
 #
 
 # TODO:
 # - Bring back save and checksum with new dialog interface (only offers to do
 #   so if ran by root, otherwise silently remove the options). Also only allow
 #   saving per-port options (known or unknown), and only when accepted.
 # - Add custom restriction targets for better integration (now some files are
 #   removed from FTP if restricted for CDROM for example, as the old
 #   behavior).
 
 # The following cases are not considered:
 #
 # - Redistribution of modified distfiles, because is never done.
 # - Creating binaries from modified sources, because packages almost always
 #   contain modifications to the source, can not be autodetected (i.e.
 #   patch-* in ${FILESDIR}, post-* targets, etc), and these licenses tend to
 #   have more restrictions anyways.
 #
 
 # Integration with target sequences
 #
 # _SANITY_SEQ+=		check-license (after check-vulnerable)
 # _PATCH_SEQ+=		ask-license (before any other targets)
 # _INSTALL_SUSEQ+=	install-license (after install-desktop-entries)
 #
 # The 'check-license' target will determine if the license was accepted,
 # rejected or has to be asked later to the user in 'ask-license' (by then
 # licenses should be extracted).  The 'install-license' target installs the
 # applications' licenses, a general package license mentioning them, and a
 # restriction report (to be used by ports, scripts and similar tools).
 
 # Variables provided to the ports system and users in general, to modify the
 # behavior of the framework
 #
 # DISABLE_LICENSES			- Disable license auditing framework completely.
 # NO_LICENSES_INSTALL		- Do not install catalog, report and licenses.
 # NO_LICENSES_DIALOGS		- Disable interactive menus for asking licenses.
 
 #NO_LICENSES_INSTALL=		yes
 #NO_LICENSES_DIALOGS=		yes
 
 # Variables provided to users (can be passed to make or set in /etc/make.conf)
 #
 # LICENSES_ACCEPTED	- Accepted licenses.
 # LICENSES_REJECTED	- Rejected licenses.
 # LICENSES_GROUPS_ACCEPTED	- Accepted license groups.
 # LICENSES_GROUPS_REJECTED	- Rejected license groups.
 # LICENSES_ASK		- Require explicit user approval for all licenses not
 #					  present in previous variables (for example, stock
 #					  accepted licenses will ask confirmation).
 #
 
 # Variables provided to ports
 #
 # LICENSE			- Code of license (short name).
 # LICENSE_PERMS		- Permissions; use "none" if empty.
 # LICENSE_GROUPS	- Groups the license belongs.
 # LICENSE_NAME		- Full license name (for the reports).
 # LICENSE_FILE		- Full path to license (or use LICENSE_TEXT).
 # LICENSE_TEXT		- Text to use as a license, useful when referencing to
 #					  another place if it's not in the distfile.
 # LICENSE_DISTFILES	- Name of licensed files (defaults to ${_DISTFILES}).
 # LICENSE_COMB		- Set to "dual" or "multi", for OR/AND behavior
 # 					  (defaults to "single" if undefined, the common case)
 #
 # The following cases are supported after defining LICENSE:
 #
 # Case 1: license defined in the framework (aka "known").
 #
 # In this case the only allowed variables to set are LICENSE_FILE and
 # LICENSE_DISTFILES. The rest are managed by the framework and are not allowed
 # to change.
 #
 # Case 2: license only known by the port (aka "unknown").
 #
 # In this case LICENSE_{PERMS,NAME} are mandatory, in addition to
 # either LICENSE_FILE or LICENSE_TEXT. Optional variable is
 # LICENSE_GROUPS.
 #
 # Available components for LICENSE_PERMS:
 # dist-mirror	- Redistribution of distfile is permitted
 # 				  (like FTP mirroring; port is not RESTRICTED).
 # dist-sell		- Selling of distfile, e.g. on CD-ROM is permitted
 # 				  (port does not need to set NO_CDROM).
 # pkg-mirror	- Free redistribution of package is permitted
 # 				  (like FTP upload; port does not set NO_PACKAGE).
 # pkg-sell		- Selling of package is permitted, e.g. on CD-ROM.
 # auto-accept	- License is accepted by default, without presented
 # 				  agreement, unless the user defines LICENSES_ASK.
 #
 # Notes about permissions:
 # - Permissions use a default-deny policy (e.g. not setting "dist-mirror"
 #   means it is automatically excluded).
 # - Components can be negated by prefixing them with "no-" (like
 #   "no-pkg-sell").
 # - In case a component is present and also excluded (i.e. no-dist-sell and
 #   dist-sell together in LICENSE_PERMS), it will be excluded.
 # - XXX Currently there is no point in "no-" prefixes, as permissions are not
 #   inherited from groups. Maybe it looks more clear that way than leaving the
 #   variable empty?
 #
 # Dual/multiple licenses:
 #
 # If LICENSE_COMB is set to "dual", then LICENSE can (must, actually) have
 # more than one component. After that each license "lic" in LICENSE falls in
 # previous cases (known or unknown), but their variables are prefixed by
 # _LICENSE_ and suffixed by _lic. The main license name, perms and groups will
 # be set automatically (following appropiate logic). The idea is that any
 # license from LICENSE can be chosen to use the package.
 #
 # The case when LICENSE_COMB is set to "multi" is similar. But the idea is
 # that all of the licenses in LICENSE must be agreed to use the package.
