This program has three modes of operation: - First, is ** EXPLOSION **, or the expanding of a .LIT file into an OEBPS compliant package. - Second, is the DOWNCONVERTING of a .LIT file down to "Sealed", or DRM1 format for reading on handheld devices. - Third, is the INSCRIBING of a .LIT file which allows you to label your ebooks. DRM5 is supported if you have a "keys.txt" file that contains the private key(s) for your passport(s) in either the CLIT program directory or the current directory. This is a tool for **YOUR OWN FAIR USE** and not for stealing other people's ebooks. Please do not use this program to distrbute illegal copies of ebooks. ... that would make Baby Jesus sad.
