UNCONFIRMED  errors and comments from readers: 


[46]  Example 3-5. /autohandler;
There are two technical errors with this code.

1) <%init> is closed with </%init>, the "/" is missing from the second block.

2) As written the server throws an error (mason ver. 1.19). Variables declared in the
<%init> blocks are availible to every subsequent block *except* <%filter> blocks. In
fact <%filter> blocks only inherit global variables.

Here is the error.
Error during compilation of
/Library/WebServer/Documents/mason/weplayfaire/autohandler:
Global symbol "$path" requires explicit package name at
/Library/WebServer/Documents/mason/weplayfaire/autohandler line 89.

and the code
     81 <%init>
     82   (my $path = $r->uri) =~ s,/[^/]+$,,;
     83 </%init>
     84
     85 <%filter>
