+// Package packfile implements encoding and decoding of packfile format.
+//
+//  == pack-*.pack files have the following format:
+//
+//    - A header appears at the beginning and consists of the following:
+//
+//      4-byte signature:
+//          The signature is: {'P', 'A', 'C', 'K'}
+//
+//      4-byte version number (network byte order):
+//          GIT currently accepts version number 2 or 3 but
+//          generates version 2 only.
+//
+//      4-byte number of objects contained in the pack (network byte order)
+//
+//      Observation: we cannot have more than 4G versions ;-) and
+//      more than 4G objects in a pack.
+//
+//    - The header is followed by number of object entries, each of
+//      which looks like this:
+//
+//      (undeltified representation)
+//      n-byte type and length (3-bit type, (n-1)*7+4-bit length)
+//      compressed data
+//
+//      (deltified representation)
+//      n-byte type and length (3-bit type, (n-1)*7+4-bit length)
+//      20-byte base object name
+//      compressed delta data
+//
+//      Observation: length of each object is encoded in a variable
+//      length format and is not constrained to 32-bit or anything.
+//
+//   - The trailer records 20-byte SHA1 checksum of all of the above.
