@majorheading Synopsis

@smallexample
AX_VERY_NICE
@end smallexample

@majorheading Description

A macro to check the options of nice, in order to have a VERY_NICE
variable which runs a program at the lowest priority VERY_NICE is
undefined if we don't find the proper options, so you can safely use:

@smallexample
  @@VERY_NICE@@ mycommand
@end smallexample

in a shell script.

The VERY_NICE variable includes the placeholder NICE_VALUE that you have
to instantiate at run-time. If you give a argument to AX_VERY_NICE, it
will be used as an argument of nice for testing and included in
VERY_NICE instead of the above placeholder.
