|
|
|

=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).

|
=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.
