-#!/usr/bin/perl
-#
-# This tool will print vaguely pretty information about a pack. It
-# expects the output of "git verify-pack -v" as input on stdin.
-#
-# $ git verify-pack -v | packinfo.pl
-#
-# This prints some full-pack statistics; currently "all sizes", "all
-# path sizes", "tree sizes", "tree path sizes", and "depths".
-#
-# * "all sizes" stats are across every object size in the file;
-# full sizes for base objects, and delta size for deltas.
-# * "all path sizes" stats are across all object's "path sizes".
-# A path size is the sum of the size of the delta chain, including the
-# base object. In other words, it's how many bytes need be read to
-# reassemble the file from deltas.
-# * "tree sizes" are object sizes grouped into delta trees.
-# * "tree path sizes" are path sizes grouped into delta trees.
-# * "depths" should be obvious.
-#
-# When run as:
-#
-# $ git verify-pack -v | packinfo.pl -tree
-#
-# the trees of objects are output along with the stats. This looks
-# like:
-#
-# 0 commit 031321c6... 803 803
-#
-# 0 blob 03156f21... 1767 1767
-# 1 blob f52a9d7f... 10 1777

-# 3 blob 660e90b1... 15 1843
-# 4 blob 0cb8e3bb... 33 1876
-# 2 blob e48607f0... 311 2088
-# size: count 6 total 2187 min 10 max 1767 mean 364.50 median 51 std_dev 635.85
-# path size: count 6 total 11179 min 1767 max 2088 mean 1863.17 median 1843 std_dev 107.26
-#
-# The first number after the sha1 is the object size, the second
-# number is the path size. The statistics are across all objects in
-# the previous delta tree. Obviously they are omitted for trees of
-# one object.
-#
-# When run as:
-#
-# $ git verify-pack -v | packinfo.pl -tree -filenames
-#
-# it adds filenames to the tree. Getting this information is slow:
