## Notes
Both `jpegoptim` & `jpegtran` have almost identical optimization, so if both are installed then just `jpegtran` is used for JPG optimization. PNG optimization however will run through both `optipng` & `pngquant` (if installed) as this has definite advantages.
Both `jpegoptim` & `jpegtran` have almost identical optimization, so if both are installed then just `jpegtran` is used for JPG optimization. PNG optimization however will run through both `optipng` & `pngquant` (if installed) as this can result in better optimization.
It is highly recommended to install the necessary optimization tools, however they are not required to run goptimize.
Goptimize will remove all exif data from JPEG files, auto-rotating those that relied on it.

It will also preserve (by default) the file's original modification times (`-p=false` to disable).
