#
# Generic build profile.sh for all platforms, works in bash, sh, and ksh.
#
# Copy this file to your own area, and edit it to suit your needs.
#
# Ideally you either won't need to set the ALT_* variables because the
#   build system will find what it needs through system provided paths
#   or environment variables, or you have installed the component in the
#   recommended default path.
#
# If you find yourself forced to set an ALT_* environment variable and
#   suspect we could have figured it out automatically, please let us know.
#
# Most ALT_* directory defaults are based on being in the parent directory in
#    ALT_SLASH_JAVA, so it's possible to create for example a "C:/jdk6"
#    directory, assign that to ALT_SLASH_JAVA, and place all the components
#    in that directory. This could also minimize the ALT_* environment
#    variables you need to set.
#

#
# Assumes basic unix utilities are in the PATH already (uname, hostname, etc.).
#
# On Windows, assumes PROCESSOR_IDENTIFIER, VS71COMNTOOLS,
#   SYSTEMROOT (or SystemRoot), COMPUTERNAME (or hostname works), and
#   USERNAME is defined in the environment.
#   This profile does not rely on using vcvars32.bat and 64bit Setup.bat.
#   Uses CYGWIN cygpath to make sure paths are space-free.
#
# The JDK Makefiles may change in the future, making some of these
#   settings unnecessary or redundant.
#
# This is a working example, but may or may not work on all systems.
