+and processed as if they were directly written on the command line, in
+place of the file name.
 
-The default is C<pod>, which uses the L<Pod::Strip> module to remove all
-pod documentation, which is very fast and reduces file size a lot.

-The C<ppi> method uses L<PPI> to parse and condense the perl sources. This
-saves a lot more than just L<Pod::Strip>, and is generally safer,
-but is also a lot slower (some files take almost a minute to strip -
-F<staticperl> maintains a cache of stripped files to speed up subsequent
-runs for this reason). Note that this method doesn't optimise for raw file
-size, but for best compression (that means that the uncompressed file size
-is a bit larger, but the files compress better, e.g. with F<upx>).

-Last not least, if you need accurate line numbers in error messages,
-or in the unlikely case where C<pod> is too slow, or some module gets
-mistreated, you can specify C<none> to not mangle included perl sources in
-any way.
+In this step, modules, perl libraries (F<.pl> files) and other files are

+all L<URI> submodules that have been installed via the CPAN distribution
+are included as well, so you don't have to manually specify them.
+
+=item L<AutoLoader> splitfiles
+
+Some modules use L<AutoLoader> - less commonly (hopefully) used functions
+are split into separate F<.al> files, and an index (F<.ix>) file contains
+the prototypes.
+
+Both F<.ix> and F<.al> files will be detected automatically and added to
+the bundle.
+
+=item link libraries (F<.a> files)
+
+Modules using XS (or any other non-perl language extension compiled at
+installation time) will have a static archive (typically F<.a>). These
+will automatically be added to the linker options in F<bundle.ldopts>.
+
+Should F<staticperl> find a dynamic link library (typically F<.so>) it
+will warn about it - obviously this shouldn't happen unless you use
+F<staticperl> on the wrong perl, or one (probably wrongly) configured to
+use dynamic loading.
+
+=item extra libraries (F<extralibs.ld>)
+
+Some modules need linking against external libraries - these are found in
+F<extralibs.ld> and added to F<bundle.ldopts>.
+
+=back
+
+=item Step 4: write bundle files and optionally link a program
+
+At this point, the select files will be read, processed (stripped) and
+finally the bundle files get written to disk, and F<staticperl mkbundle>
+is normally finished. Optionally, it can go a step further and either link
+a new F<perl> binary with all selected modules and files inside, or build
+a standalone application.
+
+Both the contents of the bundle files and any extra linking is controlled
+by these options:
+
+=over 4
+
+=item C<--strip> C<none>|C<pod>|C<ppi>
+
+Specify the stripping method applied to reduce the file of the perl
+sources included.
+
+The default is C<pod>, which uses the L<Pod::Strip> module to remove all
+pod documentation, which is very fast and reduces file size a lot.
+
+The C<ppi> method uses L<PPI> to parse and condense the perl sources. This
+saves a lot more than just L<Pod::Strip>, and is generally safer,
+but is also a lot slower (some files take almost a minute to strip -
+F<staticperl> maintains a cache of stripped files to speed up subsequent
+runs for this reason). Note that this method doesn't optimise for raw file
+size, but for best compression (that means that the uncompressed file size
+is a bit larger, but the files compress better, e.g. with F<upx>).
+
+Last not least, if you need accurate line numbers in error messages,
+or in the unlikely case where C<pod> is too slow, or some module gets
+mistreated, you can specify C<none> to not mangle included perl sources in
+any way.
+
+=item C<--compress> C<none>|C<lzf>
+
+Compress each included library file with C<lzf> (default), or do not
+compress (C<none>). LZF compression typically halves the size of the
+included library data at almost no overhead, but is counterproductive if
+you are using another compression solution such as C<UPX>, so it cna be
+disabled.
+
+=item C<--perl>
+
+After writing out the bundle files, try to link a new perl interpreter. It
+will be called F<perl> and will be left in the current working
+directory. The bundle files will be removed.
+
+This switch is automatically used when F<staticperl> is invoked with the
+C<mkperl> command instead of C<mkbundle>.
+
+Example: build a new F<./perl> binary with only L<common::sense> inside -
+it will be even smaller than the standard perl interpreter as none of the
+modules of the base distribution (such as L<Fcntl>) will be included.
+
+   staticperl mkperl -Mcommon::sense
+
+=item C<--app> F<name>
+
+After writing out the bundle files, try to link a new standalone
+program. It will be called C<name>, and the bundle files get removed after
+linking it.
+
+This switch is automatically used when F<staticperl> is invoked with the
+C<mkapp> command instead of C<mkbundle>.
+
+The difference to the (mutually exclusive) C<--perl> option is that the
+binary created by this option will not try to act as a perl interpreter -
+instead it will simply initialise the perl interpreter, clean it up and
+exit.
+
+This means that, by default, it will do nothing but burn a few CPU cycles
+- for it to do something useful you I<must> add some boot code, e.g. with
+the C<--boot> option.

+
+The variables C<PERL_LIB> and C<PERL5_LIB> are always ignored because the
+startup code used by F<staticperl> overrides C<@INC> in all cases.

+=head2 EXTRA FEATURES
+
+In addition, for the embedded loading of perl files to work, F<staticperl>
+overrides the C<@INC> array.
 
-To make truly static (Linux-) libraries, you might want to have a look at
-buildroot (L<http://buildroot.uclibc.org/>).
+=head1 FULLY STATIC BINARIES - ALPINE LINUX
 
-Buildroot is primarily meant to set up a cross-compile environment (which
-is not so useful as perl doesn't quite like cross compiles), but it can also compile
-a chroot environment where you can use F<staticperl>.
-
-To do so, download buildroot, and enable "Build options => development
-files in target filesystem" and optionally "Build options => gcc
-optimization level (optimize for size)". At the time of writing, I had
-good experiences with GCC 4.4.x but not GCC 4.5.
-
-To minimise code size, I used C<-pipe -ffunction-sections -fdata-sections
--finline-limit=8 -fno-builtin-strlen -mtune=i386>. The C<-mtune=i386>
-doesn't decrease codesize much, but it makes the file much more
-compressible.
-
-If you don't need Coro or threads, you can go with "linuxthreads.old" (or
-no thread support). For Coro, it is highly recommended to switch to a
-uClibc newer than 0.9.31 (at the time of this writing, I used the 20101201
-snapshot) and enable NPTL, otherwise Coro needs to be configured with the
-ultra-slow pthreads backend to work around linuxthreads bugs (it also uses
-twice the address space needed for stacks).
-
-If you use C<linuxthreads.old>, then you should also be aware that
-uClibc shares C<errno> between all threads when statically linking. See
-L<http://lists.uclibc.org/pipermail/uclibc/2010-June/044157.html> for a
-workaround (And L<https://bugs.uclibc.org/2089> for discussion).
-
-C<ccache> support is also recommended, especially if you want
-to play around with buildroot options. Enabling the C<miniperl>
-package will probably enable all options required for a successful
-perl build. F<staticperl> itself additionally needs either C<wget>
-(recommended, for CPAN) or C<curl>.
-
-As for shells, busybox should provide all that is needed, but the default
-busybox configuration doesn't include F<comm> which is needed by perl -
-either make a custom busybox config, or compile coreutils.
-
-For the latter route, you might find that bash has some bugs that keep
-it from working properly in a chroot - either use dash (and link it to
-F</bin/sh> inside the chroot) or link busybox to F</bin/sh>, using it's
-built-in ash shell.
-
-Finally, you need F</dev/null> inside the chroot for many scripts to work
-- F<cp /dev/null output/target/dev> or bind-mounting your F</dev> will
-both provide this.
-
-After you have compiled and set up your buildroot target, you can copy
-F<staticperl> from the C<App::Staticperl> distribution or from your
-perl f<bin> directory (if you installed it) into the F<output/target>
-filesystem, chroot inside and run it.
+This section once contained a way to build fully static (including
+uClibc) binaries with buildroot. Unfortunately, buildroot no longer
+supports a compiler, so I recommend using alpine linux instead
+(L<http://alpinelinux.org/>). Get yourself a VM (e.g. with qemu), run an
+older alpine linux verison in it (e.g. 2.4), copy staticperl inside and
+use it.
+
+The reason you might want an older alpine linux is that uClibc can be
+quite dependent on kernel versions, so the newest version of alpine linux
+might need a newer kernel then you might want for, if you plan to run your
+binaries on on other kernels.
