| [B<-help>] |
| [B<-man>] |
| [B<-exit>S< >I<exitval>] |

| =head1 OPTIONS AND ARGUMENTS |
| |
| =over 8 |
| |
| =item B<-help> |
| |
| Print a brief help message and exit. |
| |
| =item B<-man> |
| |
| Print this command's manual page and exit. |
| |
| =item B<-exit> I<exitval> |
| |
| The exit status value to return. |
| |
| =item B<-output> I<outfile> |
| |
| The output file to print to. If the special names "-" or ">&1" or ">&STDOUT" |
| are used then standard output is used. If ">&2" or ">&STDERR" is used then |
| standard error is used. |
| |
| =item B<-verbose> I<level> |
| |
| The desired level of verbosity to use: |
| |
| 1 : print SYNOPSIS only |
| 2 : print SYNOPSIS sections and any OPTIONS/ARGUMENTS sections |
| 3 : print the entire manpage (similar to running pod2text) |
| |
| =item B<-pathlist> I<dirlist> |
| |
| Specifies one or more directories to search for the input file if it |
| was not supplied with an absolute path. Each directory path in the given |
| list should be separated by a ':' on Unix (';' on MSWin32 and DOS). |
| |
| =item I<file> |
| |
| The pathname of a file containing pod documentation to be output in |
| usage message format (defaults to standard input). |
| |
| =back |
| |
| =head1 DESCRIPTION |
| |
| B<pod2usage> will read the given input file looking for pod |
| documentation and will print the corresponding usage message. |
| If no input file is specified then standard input is read. |
| |
| B<pod2usage> invokes the B<pod2usage()> function in the B<Pod::Usage> |
| module. Please see L<Pod::Usage/pod2usage()>. |
