+Report information from HandBrake-generated \`.log\` files.

+Usage: $program INFO [OPTION]... [FILE|DIRECTORY]...
+
+Information types:
+    time        time spent during transcoding
+                    (sorted from short to long)
+    speed       speed of transcoding in frames per second
+                    (sorted from fast to slow)
+    bitrate     video bitrate of transcoded output
+                    (sorted from low to high)
+    ratefactor  average P-frame quantizer for transcoding
+                    (sorted from low to high)
+
+Options:
+    --reverse   reverse direction of sort
+    --unsorted  don't sort
+
+    --help      display this help and exit
+    --version   output version information and exit
+
+Results are written to standard output.
