+is known as a "VPATH" build.
 
    With a non-GNU `make', it is safer to compile the package for one
 architecture at a time in the source code directory.  After you have
 installed the package for one architecture, use `make distclean' before
 reconfiguring for another architecture.
 
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor.  Like
+this:

+you can set and what kinds of files go in them.  In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'.  Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated.  The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the `DESTDIR' variable.  For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names.  The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
 
    If the package supports it, you can cause programs to be installed
 with an extra prefix or suffix on their names by giving `configure' the
 option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.

+   Some packages offer the ability to configure how verbose the

+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved.  Use GNU `make'
+instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
+a workaround.  If GNU CC is not installed, it is therefore recommended
+to try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.

+   On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'.  It is recommended to use the following options:

+                option which mostly just causes issues (FS#31549)
+              - Add new --sysroot option and deprecate --root. This uses the
+                guest configuration instead of the host configuration, which is

+              - Do not recognize # as a comment unless it is at the beginning of
+                a line. This allows using it as a value in ini files (FS#48702)
+              - ignore comments when examining INSTALL files (FS#51916)
+              - match multi-byte user input properly (FS#47992)

+              - various small documentation updates
+              - makepkg:
+                - Reproducible build support. makepkg now respects environment
+                  SOURCE_DATE_EPOCH when creating package metadata, and unifies

+                - parseopts, srcinfo, and integrity are now part of libmakepkg
+                - consistently use coreutils for checksumming instead of openssl

RELEASE

@@ -0,0 +1,23 @@
+The following checklist should be used for making a pacman release.
+
+- Ensure "make distcheck" succeeds
+- Call a freeze to development.
+- Send translation updates to Transifex at least two weeks before a major
+  release (see below).  At this stage, strings can only be changed for a
+  major issue.
+- Update NEWS and README files
+- Pull translation updates from Transifex
+- Update version in configure.ac as described in file
+- Update doc/index.asciidoc
+- Create a signed git tag (git tag -s vX.Y.Z -m "commit message")
+- Create and sign release tarballs (generate with "make distcheck")
+- Update pacman website
+
+Transifex updates are handled using the transifex client. The basic process is:
+- Pull updates from transifex ("tx pull -a -f --minimum-perc 75")
+- Update po files ("make update-po")
+- Fix all translation errors found
+- Add any new locales to the relevant LINGUAS file
+- Optional: Make any manual changes needed (e.g. fixing spacing in a string)
+  and update po files again
+- Push updated po files to transifex ("tx push -s -t --skip")

-Here is a brief description of the files included in this directory:
-
-PKGBUILD.vim - a vim/gvim syntax file for PKGBUILDs. Colors known variable
-names, highlights common errors such as invalid characters in pkgname or
-pkgver, etc.
-
-bacman - regenerate a pacman package based on installed files and the pacman
-database entries. Useful for reuse, or possible config file extension.
-
-bash_completion - a bash completion script for pacman, install in
-/etc/bash_completion.d/ for use (but rename to something descriptive!).
-
-checkupdates - print a list of pending updates without touching the system
-sync databases (for safety on rolling release distributions).
-
-paccache - a flexible package cache cleaning utility that allows greater
-control over which packages are removed.
-
-pacdiff - a simple pacnew/pacorig/pacsave updater for /etc/.
-
-paclist - list all packages installed from a given repository. Useful for
-seeing which packages you may have installed from the testing repository,
-for instance.
-
-paclog-pkglist - lists currently installs packages based pacman's log.
-
-pacscripts - tries to print out the {pre,post}_{install,remove,upgrade}
-scripts of a given package.
-
-pacsearch - a colorized search combining both -Ss and -Qs output. Installed
-packages are easily identified with a *** and local-only packages are also
-listed.
-
-pacsysclean - lists installed packages sorted by size.
-
-rankmirrors - ranks pacman mirrors by their connection and opening speed.
-
-updpkgsums - performs an in place update of the checksums in a PKGBUILD.
-
-vimprojects - a project file for the vim project plugin.
-
-zsh_completion - a zsh completion script, install (with a rename) to
-/usr/share/zsh/site-functions/.

+BUILDINFO - Makepkg package build information file
+
+
+Synopsis
+--------
+This manual page describes the format of a BUILDINFO file found in the root of
+a package created by makepkg. The file contains a description of the package's
+build environment. The information is formatted in key-value pairs separated by
+a '=', one value per line. Arrays are represented multiple keys with the same
+value.
+
+
+Description
+-----------
+
+This is a description of the contents of version '1' of the
+BUILDINFO file format.
+
+*format*::
+	Denotes the file format version, represented by a plain positive integer.
+
+*pkgname*::
+	The name of the package.
+
+*pkgbase*::
+
+	The base name of a package, usually the same as the pkgname except for
+	split packages.
+
+*pkgver*::
+	The version of the package including pkgrel and epoch.
+
+*pkgarch*::
+	The architecture of the package.
+
+*pkgbuild_sha256sum*::
+	The sha256sum in hex format of the PKGBUILD used to build the package.
+
+*packager*::
+	The details of the packager that built the package.
+
+*builddate*::
+	The build date of the package in epoch.
+
+*builddir*::
+	The directory where the package was built.

+NAME
+----
+
+alpm-hooks - alpm hook file format
+
+SYNOPSIS
+--------
+
+--------
+[Trigger] (Required, Repeatable)
+Operation = Install|Upgrade|Remove (Required, Repeatable)
+Type = File|Package (Required)
+Target = <Path|PkgName> (Required, Repeatable)
+
+[Action] (Required)
+Description = ... (Optional)

+--------
+
+DESCRIPTION
+-----------
+
+libalpm provides the ability to specify hooks to run before or after
+transactions based on the packages and/or files being modified.  Hooks consist
+of a single '[Action]' section describing the action to be run and one or more
+'[Trigger]' section describing which transactions it should be run for.
+
+Hooks are read from files located in the system hook directory
++{datarootdir}/libalpm/hooks+, and additional custom directories specified in
+linkman:pacman.conf[5] (the default is +{sysconfdir}/pacman.d/hooks+).  The
+file names are required to have the suffix ".hook".  Hooks are run in
+alphabetical order of their file name, where the ordering ignores the suffix.
+
+TRIGGERS
+--------
+
+Hooks must contain at least one '[Trigger]' section that determines which
+transactions will cause the hook to run.  If multiple trigger sections are
+defined the hook will run if the transaction matches *any* of the triggers.
+
+*Operation =* Install|Upgrade|Remove::
+	Select the type of operation to match targets against.  May be specified
+	multiple times.  Installations are considered an upgrade if the package or
+	file is already present on the system regardless of whether the new package
+	version is actually greater than the currently installed version.  For File
+	triggers, this is true even if the file changes ownership from one package
+	to another.  Required.
+
+*Type =* File|Package::
+	Select whether targets are matched against transaction packages or files.
+	See CAVEATS for special notes regarding File triggers.  Required.
+
+*Target =* <path|package>::
+	The file path or package name to match against the active transaction.
+	File paths refer to the files in the package archive; the installation root
+	should *not* be included in the path.  Shell-style glob patterns are
+	allowed. It is possible to invert matches by prepending a file with an
+	exclamation mark. May be specified multiple times. Required.
+
+ACTIONS
+-------
+
+*Description =* ...::
+	An optional description that describes the action being taken by the
+	hook for use in front-end output.
+
+*Exec =* <command>::
+	Command to run.  Command arguments are split on whitespace.  Values
+	containing whitespace should be enclosed in quotes.  Required.
+
+*When =* PreTransaction|PostTransaction::
+	When to run the hook.  Required.
+
+*Depends =* <package>::
+	Packages that must be installed for the hook to run. May be specified
+	multiple times.
+
+*AbortOnFail*::
+	Causes the transaction to be aborted if the hook exits non-zero.  Only
+	applies to PreTransaction hooks.
+
+*NeedsTargets*::
+	Causes the list of matched trigger targets to be passed to the running hook
+	on 'stdin'.
+
+OVERRIDING HOOKS
+----------------
+
+Hooks may be overridden by placing a file with the same name in a higher
+priority hook directory.  Hooks may be disabled by overriding them with
+a symlink to '/dev/null'.
+
+EXAMPLES
+--------
+
+--------
+# Force disks to sync to reduce the risk of data corruption
+
+[Trigger]
+Operation = Install
+Operation = Upgrade
+Operation = Remove
+Type = Package
+Target = *
+
+[Action]
+Depends = coreutils
+When = PostTransaction
+Exec = /usr/bin/sync
+--------
+
+CAVEATS
+-------
+
+There are situations when file triggers may act in unexpected ways.  Hooks are
+triggered using the file list of the installed, upgraded, or removed package.
+When installing or upgrading a file that is extracted with a '.pacnew'
+extension, the original file name is used in triggering the hook.  When
+removing a package, all files owned by that package can trigger a hook whether
+or not they were actually present on the file system before package removal.
+
+PostTransaction hooks will *not* run if the transaction fails to complete for
+any reason.

+===================
+
+Name
+----
+makepkg-template - package build templating utility
+
+
+Synopsis
+--------
+'makepkg-template' [options]
+
+
+Description
+-----------
+'makepkg-template' is a script to ease the work of maintaining multiple similar
+PKGBUILDs.  It allows you to move most of the code from the PKGBUILD into a
+template file and uses markers to allow in-place updating of existing PKGBUILDs
+if the template has been changed.
+
+Template files can contain any code allowed in a PKGBUILD. You can think of
+them like external files included with "." or "source", but they will be
+inlined into the PKGBUILD by 'makepkg-template' so you do not depend on the
+template file when building the package.
+
+Markers are bash comments in the form of:
+
+	# template start; key=value; key2=value2; ...
+
+and
+
+	# template end;
+
+Currently used keys are: name (mandatory) and version. Template names are limited to
+alphanumerics, "@", "+", ".", "-", and "_". Versions are limited to numbers and ".".
+
+For initial creation there is a one line short cut which does not need an end marker:
+
+	# template input; key=value;
+
+Using this short-cut will result in 'makepkg-template' replacing it with start
+and end markers and the template code on the first run.
+
+Template files should be stored in one directory and filenames should be
+"$template_name-$version.template" with a symlink "$template_name.template"
+pointing to the most recent template. If the version is not set in the marker,
+'makepkg-template' will automatically use the target of "$template_name.template",
+otherwise the specified version will be used.  This allows for easier
+verification of untrusted PKGBUILDs if the template is trusted. You verify the
+non-template code and then use a command similar to this:
+
+	diff -u <(makepkg-template -o -) PKGBUILD
+
+Template files may also contain markers leading to nested templates in the
+resulting PKGBUILD. If you use markers in a template, please set the version
+you used/tested with in the start/input marker so other people can properly
+recreate from templates.
+
+

+
+*-o, \--output* <build script>::
