# Usage:
#    jtdiff ...args....
#
# jtdiff requires a version of Java equivalent to JDK 1.5.0 or higher.

# $JT_HOME can be used to specify the jtdiff installation directory
#   (e.g. /usr/local/java/jct-tools/3.2.2)
#
# $JT_JAVA is used to specify the version of java to use when running JavaTest
#   (e.g. /usr/local/java/jdk1.5.0/solaris-sparc/bin/java)
#
# jtdiff also provides an Ant task for direct invocation from Ant.

# Separate out -J* options for the JVM
# Unset IFS and use newline as arg separator to preserve spaces in args
DUALCASE=1  # for MKS: make case statement case-sensitive (6709498)
