Comment:

 kelson: You just open a file descriptor on your file which has the Xapian
 DB embedded, `lseek()` it to where the Xapian DB starts, and then pass the
 file descriptor to the `Xapian::Database` constructor (instead of a
 filename) - Xapian just looks where the descriptor's file position already
 is.

 The "pack-single-file-glass-db" script is now superseded - this
 functionality has been folded into database compaction, so you can just
 use xapian-compact or the compaction API.

 Hoping to get this merged for 1.3.4, though could conceivably be 1.3.5.
