# SYNOPSIS

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