+**                      the file to be accessed.
+**      method          is the method for which access is wanted.
+**
+** ALC FILE FORMAT:
+**
+**      template : method, method, ... : group@addr, user, group, ...
+**
+**      The last item is in fact in exactly the same format as
+**      group definition in group file, i.e. everything that
+**      follows the 'groupname:' part,
+**      e.g.
+**              user, group, user@address, group@address,
+**              (user,group,...)@(address, address, ...)
+**
+** ON EXIT:
+**      returns         NULL, if there is no entry for the file in the ACL,
+**                      or ACL doesn't exist.
+**                      If there is, a GroupDef object containing the
+**                      group and user names allowed to access the file
+**                      is returned (this is automatically freed
+**                      next time this function is called).
+** IMPORTANT:
+**      Returns the first entry with matching template and
+**      method. This function should be called multiple times
+**      to process all the valid entries (until it returns NULL).
+**      This is because there can be multiple entries like:
+**
+**              *.html : get,put : ari,timbl,robert
+**              *.html : get     : jim,james,jonathan,jojo
+**
+** NOTE:
+**      The returned group definition may well contain references
+**      to groups defined in group file. Therefore these references
+**      must be resolved according to that rule file by function
+**      HTAA_resolveGroupReferences() (group file is read in by
+**      HTAA_readGroupFile()) and after that access authorization
+**      can be checked with function HTAA_userAndInetGroup().
