53 podchecker - check the syntax of POD format documentation files
57 B<podchecker> [B<-help>] [B<-man>] [B<-(no)warnings>] [I<file>S< >...]
59 =head1 OPTIONS AND ARGUMENTS
65 Print a brief help message and exit.
69 Print the manual page and exit.
71 =item B<-warnings> B<-nowarnings>
73 Turn on/off printing of warnings. Repeating B<-warnings> increases the
74 warning level, i.e. more warnings are printed. Currently increasing to
75 level two causes flagging of unescaped "E<lt>,E<gt>" characters.
79 The pathname of a POD file to syntax-check (defaults to standard input).
85 B<podchecker> will read the given input files looking for POD
86 syntax errors in the POD documentation and will print any errors
87 it find to STDERR. At the end, it will print a status message
88 indicating the number of errors found.
90 Directories are ignored, an appropriate warning message is printed.
92 B<podchecker> invokes the B<podchecker()> function exported by B<Pod::Checker>
93 Please see L<Pod::Checker/podchecker()> for more details.
97 B<podchecker> returns a 0 (zero) exit status if all specified
102 B<podchecker> returns the exit status 1 if at least one of
103 the given POD files has syntax errors.
105 The status 2 indicates that at least one of the specified
106 files does not contain I<any> POD commands.
108 Status 1 overrides status 2. If you want unambigouus
109 results, call B<podchecker> with one single argument only.
