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