Compress all JPG/JPEG files in a directory tree (simple console application)

I needed a quick application to increase the compression of all .jpg files in a directory tree. This application is a console program that takes three command-line parameters:

compressjpg inDir outDir compressionLevel extensions

compressLevel is a number from 0 to 100, where 0 is maximum compression and 100 is no compression. extensions is a comma/semi-colon delimited list of file extensions to process. For example:

C:> compressjpg c:\myfiles c:\newfiles 80 jpg;jpeg
