# description: small bash script for pdf shrink. please backup your files. all files will be overwritten, there will be no new filename etc.
# maybe you find the place to change this. i don't want new files... ;-)
# always backup your files before shrinking the pdf files. in some cases you get bigger files than smaller ones.
# please check after each shrinking...
# happy shrinking...
