56 B<podchecker> [B<-help>] [B<-man>] [B<-(no)warnings>] [I<file>S< >...]
58 =head1 OPTIONS AND ARGUMENTS
64 Print a brief help message and exit.
68 Print the manual page and exit.
70 =item B<-warnings> B<-nowarnings>
72 Turn on/off printing of warnings.
76 The pathname of a POD file to syntax-check (defaults to standard input).
82 B<podchecker> will read the given input files looking for POD
83 syntax errors in the POD documentation and will print any errors
84 it find to STDERR. At the end, it will print a status message
85 indicating the number of errors found.
87 B<podchecker> invokes the B<podchecker()> function exported by B<Pod::Checker>

92 B<podchecker> returns a 0 (zero) exit status if all specified
97 B<podchecker> returns the exit status 1 if at least one of
