freebsd-ports/Mk/Uses/uniquefiles.mk
Marcus von Appen 78b8b9e4ba New USES=uniquefiles to make files or directories unique 
by adding a prefix or suffix to them.

Files listed in UNIQUE_PREFIX_FILES will receive the prefix
set via UNIQUE_PREFIX. The same applies to UNIQUE_SUFFIX_FILES,
but with the chosen UNIQUE_SUFFIX. UNIQUE_PREFIX and
UNIQUE_SUFFIX are set to PKGNAMEPREFIX and PKGNAMESUFFIX by
default.
The uniquefiles USES enables ports to name files in special
ways, e.g. by outlining that the port does not support X11
(-nox11). A binary named bin/foo thus can be easily renamed
to bin/foo-featureA via

USES=                 uniquefiles
UNIQUE_SUFFIX=        -featureA
UNIQUE_SUFFIX_FILES=  bin/foo

The uniquefiles USES automatically adjusts the plist at
installation time. There is no need to consider the prefix
or suffix in the pkg-plist file itself. If the original name
of the renamed file is bin/foo, this exact name should be put
into pkg-plist.

The dirs argument to USES=uniquefiles will cause certain
standard directories, such as DOCSDIR or EXAMPLESDIR to be
prepended with the UNIQUE_PREFIX. The change to the directories
will hapen prior to configuring or building the port, so that
the port Makefile as well as the port's build logic are aware
of the changed name.

Since the uniquefiles USES effectively manipulates the port's
installation and file layout, it will only be available for
stagedir-aware ports. Ports with NO_STAGE=yes will be unable
to use the uniquefiles USES.

# Make files or directories 'unique', by adding a prefix or suffix.
#
# MAINTAINER: portmgr@FreeBSD.org
#
# Feature: uniquefiles
# Usage: USES=uniquefiles or USES=uniquefiles:ARGS
# Valid ARGS: dirs
#
# dirs: The port needs a prefix (and only a prefix) based on
# UNIQUE_PREFIX for the standard directories
# DOCSDIR, EXAMPLESDIR, DATADIR, WWWDIR, ETCDIR
#
# Variables for ports:
#
# UNIQUE_PREFIX - The prefix to be used for directories and files.
# Default: ${PKGNAMEPREFIX}.
# UNIQUE_PREFIX_FILES - A list of files that need to be prefixed.
# Default: empty
# UNIQUE_SUFFIX - The suffix to be used for files.
# Default: ${PKGNAMESUFFIX}.
# UNIQUE_SUFFIX_FILES - A list of files that need to be suffixed.
# Default: empty
#
# Variables for the ports framework, but NOT individual ports:
#
# UNIQUE_DEFAULT_LINKS - When set to "yes", symlinks of the original
# filenames are also created pointing to their
# UNIQUE_* counterparts.
# This is useful for supporting multiple logical
# instances from a single physical port, but where
# you want to mark only *one* of those instances to
# provide original filenames.
#
# category/py-foo, installed as:
#
# py27-foo for Python 2.7 (DEFAULT_VERSION)
# py33-foo for Python 3.3
#
# Results in:
#
# py27-foo
# bin/foo-2.7 (UNIQUE_SUFFIX)
# bin/foo -> bin/foo-2.7 (symlinked original filename)
# py33-foo creates:
# bin/foo-3.3 (UNIQUE_SUFFIX)
#
# Default: no
#
# UNIQUE_FIND_PREFIX_FILES - A shell command to be executed to find files for
# the specific port. This has to return a
# list of files to be iterated over.
# Default: empty
#
# UNIQUE_FIND_SUFFIX_FILES - A shell command to be executed to find files for
# the specific port. This has to return a
# list of files to be iterated over.
# Default: empty
#
# NOTE: multiple logical instances are not supported by pkg and the original
# pkg_tools at the moment.
