updpkgsums: add more error checking before replacement

Re-add some paranoia which was inadvertently lost with 768b65e934. In
case 'makepkg -g' fails to generate new sums (e.g. when a remote
resource cannot be fetched), or awk fails to write the new file (i have
no idea when this would happen), bail out with an error.

    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

+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

+
+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'.

+    -m, --move <dir>      move candidate packages to "dir".
+    -r, --remove          remove candidate packages.
+
+  Options:
+    -a, --arch <arch>     scan for "arch" (default: all architectures).
+    -c, --cachedir <dir>  scan "dir" for packages. can be used more than once.
+                          (default: read from @sysconfdir@/pacman.conf).
+    -f, --force           apply force to mv(1) and rm(1) operations.
+    -h, --help            display this help message and exit.
+    -i, --ignore <pkgs>   ignore "pkgs", comma-separated. Alternatively, specify
+                          "-" to read package names from stdin, newline-
+                          delimited.
+    -k, --keep <num>      keep "num" of each package in the cache (default: 3).
+        --nocolor         remove color from output.
+    -u, --uninstalled     target uninstalled packages.
+    -v, --verbose         increase verbosity. specify up to 3 times.
+    -z, --null            use null delimiters for candidate names (only with -v

-In addition to the above directives, the optional build() function usually
-comprises the remainder of the PKGBUILD. This is directly sourced and executed
-by makepkg, so anything that bash or the system has available is available for
-use here. The function is run in `bash -e` mode, meaning any command that exits

+Packaging Functions
+-------------------
+In addition to the above directives, PKGBUILDs require a set of functions that
+provide instructions to build and install the package. As a minimum, the
+PKGBUILD must contain a `package()` function which installs all the package's
+files into the packaging directory, with optional `prepare()`, `build()`, and
+`check()` functions being used to create those files from source.
+
+*package() Function*::
+	The `package()` function is used to install files into the directory that
+	will become the root directory of the built package and is run after all
+	the optional functions listed below. When specified in combination with
+	the fakeroot BUILDENV option in linkman:makepkg.conf[5], fakeroot usage
+	will be limited to running the packaging stage. All other functions will
+	be run as the user calling makepkg.
+
+*prepare() Function*::
+	An optional `prepare()` function can be specified in which operations to
+	prepare the sources for building, such as patching, are performed. This
+	function is run after the source extraction and before the `build()`
+	function. The `prepare()` function is skipped when source extraction
+	is skipped.
+
+*build() Function*::
+	The optional `build()` function is use to compile and/or adjust the source
+	files in preparation to be installed by the `package()` function. This is
+	directly sourced and executed by makepkg, so anything that Bash or the
+	system has available is available for use here. Be sure any exotic
+	commands used are covered by the `makedepends` array.
++
+If you create any variables of your own in the `build()` function, it is
+recommended to use the Bash `local` keyword to scope the variable to inside
+the `build()` function.
+
+*check() Function*::
+	An optional `check()` function can be specified in which a package's
+	test-suite may be run. This function is run between the `build()` and
+	`package()` functions. Be sure any exotic commands used are covered by the
+	`checkdepends` array.
+
+All of the above variables such as `$pkgname` and `$pkgver` are available for
+use in the `build()` function. In addition, makepkg defines the following
 variables for use during the build and install process:
 
-*startdir*::
-	This contains the absolute path to the directory where the PKGBUILD is
-	located, which is usually the output of `$(pwd)` when makepkg is started.
-	Use of this variable is deprecated and strongly discouraged.
-
 *srcdir*::
 	This contains the directory where makepkg extracts, or copies, all source
 	files.

-Development Directives
-----------------------
-makepkg supports building development versions of packages without having to
-manually update the pkgver in the PKGBUILD. This was formerly done using the
-separate utility 'versionpkg'. In order to utilize this functionality, your
-PKGBUILD must use correct variable names depending on the SCM being fetched
-from (e.g., 'makepkg-git', 'mplayer-svn').
+Using VCS Sources[[VCS]]
+------------------------
+Building a developmental version of a package using sources from a version
+control system (VCS) is enabled by specifying the source in the form
+`source=('directory::url#fragment')`. Currently makepkg supports the Bazaar, Git,
+Subversion, and Mercurial version control systems. For other version control
+systems, manual cloning of upstream repositories must be done in the `prepare()`
+function.
 
-*CVS*::
-	The generated pkgver will be the date the package is built.
+The source URL is divided into three components:
 
-	*_cvsroot*;;
-		The root of the CVS repository.
+*directory*::
+	(optional) Specifies an alternate directory name for makepkg to download
+	the VCS source into.
 
-	*_cvsmod*;;
-		The CVS module to fetch.
+*url*::
+	The URL to the VCS repository. This must include the VCS in the URL protocol
+	for makepkg to recognize this as a VCS source. If the protocol does not
+	include the VCS name, it can be added by prefixing the URL with `vcs+`. For
+	example, using a Git repository over HTTPS would have a source URL in the
+	form:
+	`git+https://...`.
 
-*SVN*::
-	The generated pkgver will be the latest SVN revision number.
+*fragment*::
+	(optional) Allows specifying a revision number or branch for makepkg to checkout
+	from the VCS. For example, to checkout a given revision, the source line would
+	have the format `source=(url#revision=123)`. The available fragments depends on
+	the VCS being used:
 
-	*_svntrunk*;;
-		The trunk of the SVN repository.
+	*bzr*;;
+		revision (see `'bzr help revisionspec'` for details)
 
-	*_svnmod*;;

+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 most recent version of the
+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.
