__DATA__

=head1 NAME

SVK::Command::Ignore - Ignore files by setting svn:ignore property

=head1 SYNOPSIS

 ignore PATH...

=head1 DESCRIPTION

Adds the given paths to the 'svn:ignore' properties of their parents,
if they are not already there.

(If a given path contains a wildcard character (*, ?, [, or \), the
results are undefined -- specifically, the result of the check to see
if the entry is already there may not be what you expected.  Currently
it will not try to escape any such entries before adding them.)

To tell svk to start paying attention to a file again, use the command
'svk pe svn:ignore' to manually edit the ignore list.
