So you should never see an ALT_* variable defined in any 33 # makefiles, just used. This is the convention and there are some 34 # exceptions, either mistakes or unusual circumstances. 35 # 36 # The naming convention for the default value of one of these variables 37 # that has an ALT_* override capability is to name the default value with a 38 # leading underscore (_). So for XXX you would have: 39 # _XXX default value 40 # ALT_XXX any override the user is providing if any 41 # XXX the final value, either the default _XXX or the ALT_XXX value. 42 # 43 44 # On Directory names. In very rare cases should the Windows directory 45 # names use the backslash, please use the C:/ style of windows paths. 46 # Avoid duplicating the // characters in paths, this has known to cause 47 # strange problems with jar and other utilities, e.g. /a//b/ != /a/b/. 48 # Some of these variables have an explicit trailing / character, but in 49 # general, they should NOT have the trailing / character. 50 51 #
