It looks like you're stuck with "Usage:". The source code for
Pod::Usage seems to change your "SYNOPSIS" to "USAGE" then lowercase it and append the colon:
sub preprocess_paragraph {
my $self = shift;
local($_) = shift;
## See if this is a heading and we arent printing the entire manpa
+ge.
if (($self->{VERBOSE} < 2) && /^=head/o) {
## Change the title of the SYNOPSIS section to USAGE
s/^=head1\s+SYNOPSIS\s*$/=head1 USAGE/o;
## Try to do some lowercasing instead of all-caps in headings
s{([A-Z])([A-Z]+)}{((length($2) > 2) ? $1 : lc($1)) . lc($2)}g
+e;
## Use a colon to end all headings
s/\s*$/:/o unless (/:\s*$/o);
}
return $self->SUPER::preprocess_paragraph($_);
}
