Note
:
This
is
part
of
the
set
of
autoconf
M4
macros
for
Java
dnl
programs
.
It
is
VERY
IMPORTANT
that
you
download
the
whole
set
,
dnl
some
macros
depend
on
other
.
Unfortunately
,
the
autoconf
archive
dnl
does
not
support
the
concept
of
set
of
macros
,
so
I
had
to
break
it
dnl
for
submission
.
The
general
documentation
,
as
well
as
the
sample
dnl
configure
.
in
,
is
included
in
the
AC_PROG_JAVA
macro
.
