=head1 NAME

podchecker - check the syntax of POD format documentation files

=head1 SYNOPSIS

B<podchecker> [B<-help>] [B<-man>] [B<-(no)warnings>] [I<file>S< >...]

=head1 OPTIONS AND ARGUMENTS

=over 8

=item B<-help>

Print a brief help message and exit.

=item B<-man>

Print the manual page and exit.

=item B<-warnings> B<-nowarnings>

Turn on/off printing of warnings. Repeating B<-warnings> increases the
warning level, i.e. more warnings are printed. Currently increasing to
level two causes flagging of unescaped "E<lt>,E<gt>" characters.

=item I<file>

The pathname of a POD file to syntax-check (defaults to standard input).

=back

=head1 DESCRIPTION

B<podchecker> will read the given input files looking for POD
syntax errors in the POD documentation and will print any errors
it find to STDERR. At the end, it will print a status message
indicating the number of errors found.

Directories are ignored, an appropriate warning message is printed.

B<podchecker> invokes the B<podchecker()> function exported by B<Pod::Checker>
Please see L<Pod::Checker/podchecker()> for more details.

=head1 RETURN VALUE

B<podchecker> returns a 0 (zero) exit status if all specified
POD files are ok.

=head1 ERRORS

B<podchecker> returns the exit status 1 if at least one of
the given POD files has syntax errors.

The status 2 indicates that at least one of the specified 
files does not contain I<any> POD commands.

Status 1 overrides status 2. If you want unambiguous
results, call B<podchecker> with one single argument only.
