=head1 DESCRIPTION
F<perlcc> creates standalone executables from Perl programs, using the
code generators provided by the L<B> module. At present, you may
either create executable Perl bytecode, using the C<-B> option, or
generate and compile C files using the standard and 'optimised' C
backends.
The code generated in this way is not guaranteed to work. The whole
codegen suite (C<perlcc> included) should be considered B<very>
experimental. Use for production purposes is strongly discouraged.
=head1 OPTIONS
=over 4
=item -LI<C library directories>
Adds the given directories to the library search path when C code is
passed to your C compiler.
=item -II<C include directories>
Adds the given directories to the include file search path when C code is
passed to your C compiler; when using the Perl bytecode option, adds the
given directories to Perl's include path.
=item -o I<output file name>
Specifies the file name for the final compiled executable.
Without given output file name we use the base of the input file,
or with C<-e> F<a.out> resp. F<a.exe> and a randomized intermediate
C filename.
If the input file is an absolute path on a non-windows system use
the basename.
=item -c I<C file name>
Create C code only; do not compile to a standalone binary.
=item -e I<perl code>
Compile a one-liner, much the same as C<perl -e '...'>
=item -S
"Keep source".
Do not delete generated C code after compilation.
=item -B
Use the Perl bytecode code generator.
=item -O
Use the 'optimised' C code generator B::CC. This is more experimental than
everything else put together, and the code created is not guaranteed to
compile in finite time and memory, or indeed, at all.
=item -OI<1-4>
Pass the numeric optimisation option to the compiler backend.
Shortcut for C<-Wb=-On>.
This does not enforce B::CC.
=item -v I<0-6>
Set verbosity of output from 0 to max. 6.
=item -r
Run the resulting compiled script after compiling it.
=item --log I<logfile>
Log the output of compiling to a file rather than to stdout.
=item -f<option> or --f=<option>
Pass the options to the compiler backend, such as
C<-fstash> or C<-fno-delete-pkg>.
=item --Wb=I<options>
Pass the options to the compiler backend, such as C<--Wb=-O2,-v>
=item --Wc=I<options>
Pass comma-seperated options to cc.
=item --Wl=I<options>
Pass comma-seperated options to ld.
=item -T or -t
run the backend using perl -T or -t
=item -u package
Add package(s) to compiler and force linking to it.
=item -U package
Skip package(s). Do not compile and link.
=item --stash
Detect external packages automatically via B::Stash
=item --static
Link to static libperl.a
=item --staticxs
Link to static XS if available.
If the XS libs are only available as shared libs link to those ("prelink").
Systems without rpath (windows, cygwin) must be extend LD_LIBRARY_PATH/PATH at run-time.
Together with -static, purely static modules and no run-time eval or
require this will gain no external dependencies.
=item --shared
Link to shared libperl
=item --sharedxs
Link shared XSUBs if the linker supports it. No DynaLoader needed.
This will still require the shared XSUB libraries to be installed
at the client, modification of @INC in the source is probably required.
(Not yet implemented)
=item -m|--sharedlib [Modulename]
Create a module, resp. a shared library.
Currently only enabled for Bytecode and CC. I<(not yet tested)>
=item --testsuite
Tries be nice to Test:: modules, like preallocating the file
handles 4 and 5, and munge the output of BEGIN.
perlcc -r --testsuite t/harness
=item --time
Benchmark the different phases B<c> I<(B::* compilation)>,
B<cc> I<(cc compile + link)>, and B<r> (runtime).
=item --no-spawn
Do not spawn subprocesses for compilation, because broken
shells might not be able to kill its children.
