+dnl Look for a program to use as VARIABLE. If --with-VARIABLE is given, then
+dnl set VARIABLE to the path provided there (WITH-ARG and HELP-STRING are
+dnl used for --help output). Otherwise, set VARIABLE to the first of
+dnl PROGS-TO-CHECK-FOR on the path; if none of those is found, leave
+dnl VARIABLE unchanged.
+dnl If the program was found, define HAVE_WITH-ARG.
