Suggestionen for man page addition

[Hans Ulrich Niedermann <nospam@thanx>]

Hi Denis,

debugging my wml based web site, I had to use the -v9 option to wml
several times and each time I was annoyed that the pager started was
more and not less. Then I looked at the wml source and found that wml
uses more environment variables than wml(1) says. Therefore I suggest
to add the following variable descriptions (or something similar) to 
the ENVIRONMENT section of wml(1) under USED VARIABLES:

       PAGER
           This variable contains the pager WML is to use. WML uses
           a pager when called with the --verbose=NUM or -vNUM option 
           respectively and NUM is 3 or higher and therefore showing 
           the processed data after each pass. Default is 'more'.

       TMPDIR
           This variable contains the directory WML stores its 
           temporary files in. Default is '/tmp'.

BTW, I found these variables running "grep ENV `which wml`".

Bye,

Uli
