386Include the named module and trace direct dependencies. This is done by 397Include the named module or perl library and trace direct

388and files it actually loads. 399tracing which other modules and files it actually loads.

394Sometimes you want to load old-style "perl libraries" (F<.pl> files), 405Sometimes you want to load old-style "perl libraries" (F<.pl> files), or
395or maybe other weirdly named files. To do that, you need to quote 406maybe other weirdly named files. To support this, the C<--use> option
396the name in single or double quotes (this is because F<staticperl> 407actually tries to do what you mean, depending on the string you specify:
397I<literally> just adds the string after the C<require> - which acts 408
398different when confronted with quoted vs. unquoted strings). When given on 409=over 4
399the command line, you probably need to quote once more to avoid your shell 410
400interpreting it. Common cases that need this are F<Config_heavy.pl> and 411=item a possibly valid module name, e.g. F<common::sense>, F<Carp>,
401F<utf8_heavy.pl>. 412F<Coro::Mysql>.
413
414If the string contains no quotes, no F</> and no F<.>, then C<--use>
415assumes that it is a normal module name. It will create a new package and
416evaluate a C<use module> in it, i.e. it will load the package and do a
417default import.
418
419The import step is done because many modules trigger more dependencies
420when something is imported than without.
421
422=item anything that contains F</> or F<.> characters,
423e.g. F<utf8_heavy.pl>, F<Module/private/data.pl>.
424
425The string will be quoted and passed to require, as if you used C<require
426$module>. Nothing will be imported.
427
428=item "path" or 'path', e.g. C<"utf8_heavy.pl">.
429
430If you enclose the name into single or double quotes, then the quotes will
431be removed and the resulting string will be passed to require. This syntax
432is form compatibility with older versions of staticperl and should not be
433used anymore.

436
437Example: C<use> AnyEvent::Socket, once using C<use> (importing the
438symbols), and once via C<require>, not importing any symbols. The first
439form is preferred as many modules load some extra dependencies when asked
440to export symbols.

728=item C<--ignore-env>
729
730Generates extra code to unset some environment variables before
731initialising/running perl. Perl supports a lot of environment variables
732that might alter execution in ways that might be undesirablre for
733standalone applications, and this option removes those known to cause
734trouble.
735
736Specifically, these are removed:
737
738C<PERL_HASH_SEED_DEBUG> and C<PERL_DEBUG_MSTATS> can cause underaible
739output, C<PERL5OPT>, C<PERL_DESTRUCT_LEVEL>, C<PERL_HASH_SEED> and
740C<PERL_SIGNALS> can alter execution significantly, and C<PERL_UNICODE>,
741C<PERLIO_DEBUG> and C<PERLIO> can affect input and output.
742
743The variables C<PERL_LIB> and C<PERL5_LIB> are always ignored because the
744startup code used by F<staticperl> overrides C<@INC> in all cases.
745
746This option will not make your program more secure (unless you are
747running with elevated privileges), but it will reduce the surprise effect
748when a user has these environment variables set and doesn't expect your
749standalone program to act like a perl interpreter.

1067When your bootcode already wants to access some XS functions at
1068compiletime, then you need to supply an C<xs_init> function pointer that
1069is called as soon as perl is initialised enough to define XS functions,
1070but before the preamble code is executed:
