dist/orig contains the stock sqlite3 code, as packaged in the ZIP file above.
dist contains a copy of dist/orig, but with the Android.patch file applied.
Please see Android.patch for a list of differences between stock and
Android.
The Android specific patch applied cleanly and was regenerated.
This very minor release contains a performance enhancement to the page-cache "truncate" operation.
More details about the release is avaliable here: http://sqlite.com/releaselog/3_14_1.html
