# Normally the convention is that these alternate definitions of

#   primary make variables are never defined inside the Makefiles anywhere

#   but are defined via environment variables or set on the make command

#   line. So you should never see an ALT_* variable defined in any

#   makefiles, just used. This is the convention and there are some

#   exceptions, either mistakes or unusual circumstances.

#

# The naming convention for the default value of one of these variables

#   that has an ALT_* override capability is to name the default value with a

#   leading underscore (_). So for XXX you would have:

#      _XXX      default value

#      ALT_XXX   any override the user is providing if any

#      XXX       the final value, either the default _XXX or the ALT_XXX value.

#

# On Directory names. In very rare cases should the Windows directory

#    names use the backslash, please use the C:/ style of windows paths.

#    Avoid duplicating the // characters in paths, this has known to cause

#    strange problems with jar and other utilities, e.g. /a//b/ != /a/b/.

#    Some of these variables have an explicit trailing / character, but in

#    general, they should NOT have the trailing / character.
