To produce `last modified' info texts you can use variables (pass 2
like WML_SRC_ISOTIME. There is also variable
WML_SRC_FILENAME, WML_SRC_DIRNAME and othes. See wml man page or

   http://www.thewml.org/docs/frontend/wml.html#environment

An example:

file template.wml:

# this is template.wml
<:

# get caller name
$caller = $WML_SRC_FILENAME;

# do something interesting with $caller
print $caller;

:>

file page.wml:
#include "template.wml"
HELLO


Now

$ wml template.wml
template.wml
