=head1 NAME
File::Slurp::Tiny - A simple, sane and efficient file slurper
=head1 VERSION
version 0.003
=head1 SYNOPSIS
use File::Slurp::Tiny 'read_file';
my $content = read_file($filename);
=head1 DESCRIPTION
This module provides functions for fast and correct slurping and spewing. All functions are optionally exported.
=head1 FUNCTIONS
=head2 read_file($filename, %options)
Reads file C<$filename> into a scalar. By default it returns this scalar. Can optionally take these named arguments:
=over 4
=item * binmode
Set the layers to read the file with. The default will be something sensible on your platform.
=item * buf_ref
Pass a reference to a scalar to read the file into, instead of returning it by value. This has performance benefits.
=item * scalar_ref
If set to true, C<read_file> will return a reference to a scalar containing the file content.
=back
=head2 read_lines($filename, %options)
Reads file C<$filename> into a list/array. By default it returns this list. Can optionally take these named arguments:
=over 4
=item * binmode
Set the layers to read the file with. The default will be something sensible on your platform.
=item * array_ref
Pass a reference to an array to read the lines into, instead of returning them by value. This has performance benefits.
=item * chomp
C<chomp> the lines.
=back
=head2 write_file($filename, $content, %options)
Open C<$filename>, and write C<$content> to it. Can optionally take this named argument:
=over 4
=item * binmode
Set the layers to write the file with. The default will be something sensible on your platform.
=back
=head2 read_dir($dirname, %options)
Open C<dirname> and return all entries except C<.> and C<..>. Can optionally take this named argument:
=over 4
=item * prefix
This will prepend C<$dir> to the entries
=back
=head1 SEE ALSO
=over 4
=item * L<Path::Tiny>
A minimalistic abstraction not only around
=item * L<File::Slurp>
Another file slurping tool.
