// Read a tabular cross-reference file generated by ctags, then read a list of
// html files generated by Vim's TOhtml command on C++ code. Link words
// in the html files to cross-references from ctags.

// Usage:
//    linkify [tags file] [html files]...

// Still plenty of holes:
// - unnecessarily linking definition location to itself
// - can't detect strings in spite of attempt to support them below, because
//   Vim's generated html turns quotes into html entities
// - distinguishing function and variable names
// - distinguishing Mu code in C++ files
// - distinguishing between function overloads
//   - if there's duplicate tags we aren't smart enough to distinguish between
//     them yet, so we simply don't add any link at all
//   - but even that's not perfect, because sometimes the tags file has a
//     single definition but there's still multiple overloads (say I defined
//     'clear()' on some type, and it's already defined on STL classes)
// - ctags misses some symbols in layered code
