# SYNOPSIS
|
||
|
|
#
|
||
|
|
# AX_CHECK_CLASS
|
||
|
|
#
|
||
|
|
# DESCRIPTION
|
||
|
|
#
|
||
|
|
# AX_CHECK_CLASS tests the existence of a given Java class, either in a
|
||
|
|
# jar or in a '.class' file.
|
||
|
|
#
|
||
|
|
# *Warning*: its success or failure can depend on a proper setting of the
|
||
|
|
# CLASSPATH env. variable.
|
||
|
|
#
|
||
|
|
# 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.
