! 81: * XXX - how should we distinguish Java from C++?
! 82: * The trick used in a Debian snapshot, of having "extends" or "implements"
! 83: * as tags for Java, doesn't work very well, given that those keywords
! 84: * are often preceded by "class", which flags it as C++.
! 85: *
! 86: * Perhaps we need to be able to say
! 87: *
! 88: * If "class" then
! 89: *
! 90: * if "extends" or "implements" then
! 91: * Java
! 92: * else
! 93: * C++
! 94: * endif
! 95: *
! 96: * Or should we use other keywords, such as "package" or "import"?
! 97: * Unfortunately, Ada95 uses "package", and Modula-3 uses "import",
! 98: * although I infer from the language spec at
! 99: *
! 100: * http://www.research.digital.com/SRC/m3defn/html/m3.html
! 101: *
! 102: * that Modula-3 uses "IMPORT" rather than "import", i.e. it must be
! 103: * in all caps.
! 104: *
! 105: * So, for now, we go with "import". We must put it before the C++
! 106: * stuff, so that we don't misidentify Java as C++. Not using "package"
! 107: * means we won't identify stuff that defines a package but imports
! 108: * nothing; hopefully, very little Java code imports nothing (one of the
! 109: * reasons for doing OO programming is to import as much as possible
! 110: * and write only what you need to, right?).
! 111: *
! 112: * Unfortunately, "import" may cause us to misidentify English text
! 113: * as Java, as it comes after "the" and "The". Perhaps we need a fancier
! 114: * heuristic to identify Java?
