xs maps

[Torsten Foertsch]

Hi,

can someone shed some light on the first characters in *_structures.map files? 
For example in 

<apr_bucket_type_t>
<  name
-  num_func
...
</apr_bucket_type_t>

<apr_bucket>
>  link
<  type
...
</apr_bucket>

<apr_bucket_brigade>
~  pool
...
</apr_bucket_brigade>
...
<apr_uri_t>
&  scheme
   hostinfo
...
-  dns_resolved
</apr_uri_t>

What do these [ $%><~-?&!] mean?

$ perl -MData::Dumper -ne '/^(.)\s/ and $h{$1}++; END{print Dumper(\%h)}' 
*_structures.map
$VAR1 = {
          '$' => 10,
          ' ' => 134,
          '%' => 6,
          '#' => 6,
          '>' => 24,
          '~' => 14,
          '-' => 48,
          '?' => 2,
          '&' => 14,
          '<' => 81,
          '!' => 12
        };

Torsten
