=head1 NAME

Pod::Perldoc::ToTerm - render Pod with terminal escapes

=head1 SYNOPSIS

  perldoc -o term Some::Modulename

=head1 DESCRIPTION

This is a "plug-in" class that allows Perldoc to use
Pod::Text as a formatter class.

It supports the following options, which are explained in
L<Pod::Text>: alt, indent, loose, quotes, sentence, width

For example:

  perldoc -o term -w indent:5 Some::Modulename

=head1 PAGER FORMATTING

Depending on the platform, and because this class emits terminal escapes it
will attempt to set the C<-R> flag on your pager by injecting the flag into
your environment variable for C<less> or C<more>.

On Windows and DOS, this class will not modify any environment variables.

=head1 CAVEAT

This module may change to use a different text formatter class in the
future, and this may change what options are supported.
