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?
