13.1 Printing error messages
============================
You can print error messages using `errprint':
-- Builtin: errprint (MESSAGE, ...)
Prints MESSAGE and the rest of the arguments on the standard error
output, separated by spaces.
The expansion of `errprint' is void. The macro `errprint' is
recognized only with parameters.
errprint(`Invalid arguments to forloop
')
error-->Invalid arguments to forloop
=>
A trailing newline is _not_ printed automatically, so it must be
supplied as part of the argument, as in the example. BSD
implementations of `m4' do append a trailing newline on each `errprint'
call, while some other implementations only print the first argument.
