Repeating B<-warnings> increases the warning level, i.e. more warnings are printed. Currently increasing to level two causes flagging of unescaped "E,E" characters. =item I The pathname of a POD file to syntax-check (defaults to standard input). =back =head1 DESCRIPTION B 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 invokes the B function exported by B Please see L for more details. =head1 RETURN VALUE B returns a 0 (zero) exit status if all specified POD files are ok. =head1 ERRORS B 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 POD commands. Status 1 overrides status 2. If you want unambiguous results, call B with one single argument only. =head1 SEE ALSO L and L =head1 AUTHORS Please report bugs using L.
