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