[Groff] man page in perlscript

[Daniel Schroeter]

hi,
hope that's the correct place here...
i using GNU troff version 1.16.1 under linux 2.4.1
we have here perlscripts, where the manpage is included.

#!/usr/bin/perl -w
'di';
'ig00';
# here is starting the perlscript
....
....

'di                     \" finish diversion--previous line must be blank
nr nl 0-1               \" fake up transition to first page again
.nr % 0                 \" start at page 1

-------------------and so on ----------------

under hpux, sun and aix it works fine. bit if i using "man 
<programname>" under linux, i get this:

<standard input>:3: warning: `di';' not defined (probable missing space 
after `di')
<standard input>:4: warning: `ig00';' not defined (probable missing 
space after
`ig')
<standard input>:171: cannot use character `*' as a starting delimiter
<standard input>:172: division by zero
<standard input>:173: warning: numeric expression expected (got `b')
#!/bag/local/bin/perl -w
....
....
....


what's the problem? is it groff? if i using "groff -man <programname>" 
it's the same (only more error messages).
please help, i'm a newbie ;-)
THNX
BTW: where can i found a good documentation about the syntax from manpages?
