No documentation, unfortunately.  The Sparse ctags doesn't take any
options.  It should work on multiple files by simply giving all the
files on one ctags command line, with something like:
ctags $(find -name '*.c')

However, it seems to have some problems at the moment running on even
*one* file:

$ ./ctags ctags.c
unknown symbol const namespace:2 type:17

$ ./ctags validation/context.c
unknown symbol const namespace:2 type:17

type 17 refers to SYM_KEYWORD, which seems consistent with "unknown
symbol const", though I don't know why ctags would look at const as a
symbol.

I've CCed Christopher Li, the author of the Sparse ctags implementation.
Chris, can you look into this problem and suggest a possible solution?
