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