=head1 NAME
sponge - Soak up standard input and write to a file (perl implementation)
=head1 VERSION
This document describes version 0.003 of sponge (from Perl distribution App-sponge), released on 2023-02-15.
=head1 SYNOPSIS
 % sed '...' file | grep '...' | sponge [-a] file
=head1 DESCRIPTION
This is a simple perl implementation for the Unix utility B<sponge>. See its
documentation for more details. Any deviation of behavior compared to the
original C<sponge> is assumed as bug and can be reported.
=head1 TODO
BUG: Our C<-a> implementation is not atomic.
=head1 HOMEPAGE
Please visit the project's homepage at L<https://metacpan.org/release/App-sponge>.
=head1 SOURCE
Source repository is at L<https://github.com/perlancar/perl-App-sponge>.
=head1 SEE ALSO
The original implementation of B<sponge>, L<http://joeyh.name/code/moreutils/>.

perlancar <perlancar@cpan.org>
=head1 CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull requests on
GitHub.
Most of the time, you don't need to build the distribution yourself. You can
simply modify the code, then test via:
 % prove -l
If you want to build the distribution (e.g. to try to install it locally on your
system), you can install L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<Pod::Weaver::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond
that are considered a bug and can be reported to me.

=head1 BUGS
Please report any bugs or feature requests on the bugtracker website L<https://rt.cpan.org/Public/Dist/Display.html?Name=App-sponge>
When submitting a bug or request, please include a test-file or a
patch to an existing test-file that illustrates the bug or desired
feature.
