NAME
       perlcc - generate executables from Perl programs

SYNOPSIS
           $ perlcc hello              # Compiles into executable 'a.out'
           $ perlcc -o hello hello.pl  # Compiles into executable 'hello'

           $ perlcc -O file            # Compiles using the optimised C backend
           $ perlcc -B file            # Compiles using the bytecode backend

           $ perlcc -c file            # Creates a C file, 'file.c'
           $ perlcc -S -o hello file   # Creates a C file, 'file.c',
                                       # then compiles it to executable 'hello'
           $ perlcc -c out.c file      # Creates a C file, 'out.c' from 'file'

           $ perlcc -e 'print q//'     # Compiles a one-liner into 'a.out'
           $ perlcc -c -e 'print q//'  # Creates a C file 'a.out.c'

           $ perlcc -r hello           # compiles 'hello' into 'a.out', runs 'a.out'.

           $ perlcc -r hello a b c     # compiles 'hello' into 'a.out', runs 'a.out'.
                                       # with arguments 'a b c'

           $ perlcc hello -log c       # compiles 'hello' into 'a.out' logs compile
                                       # log into 'c'.


DESCRIPTION
       perlcc creates standalone executables from Perl programs,
       using the code generators provided by the the B manpage
       module. At present, you may either create executable Perl
       bytecode, using the "-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 ("perlcc" included) should be con-
       sidered very experimental. Use for production purposes is
       strongly discouraged.

OPTIONS
       -Llibrary directories
           Adds the given directories to the library search path
           when C code is passed to your C compiler.

       -Iinclude 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 direc-
           tories to Perl's include path.

       -o output file name
           Specifies the file name for the final compiled exe-
           cutable.

       -c C file name
           Create C code only; do not compile to a standalone
           binary.

       -e perl code
           Compile a one-liner, much the same as "perl -e '...'"

       -S  Do not delete generated C code after compilation.

       -B  Use the Perl bytecode code generator.

       -O  Use the 'optimised' C code generator. 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.

       -v  Increase verbosity of output; can be repeated for more
           verbose output.

       -r  Run the resulting compiled script after compiling it.

       -log
           Log the output of compiling to a file rather than to
           stdout.
