#
# 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, cannot 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.
