EXAMPLES

% sp_smaps_diff --level=3 *after_boot*.csv

Shows difference of smaps snapshots at memory usage down
to level of mapping types (code, data, anon).

Writes diff in csv format using level 0.

% sp_smaps_diff *after_boot*.cap -o boot_diff.pid.html

Writes diff in html using level 2.

path has some of the following components:
.sys -> 0
.app -> 1
.pid -> 2
.sec -> 3
.obj -> 4
