Added options -dep, -list, and -info. Update does a search for the file, lists the downloaded results, and reads them. Thus "update -info gnumeric" will list "gnumeric.tcz.info" and read it to terminal. "update -info vim" will list:
vim-7.2-bin.tcz.info vim_7.2.245.tcz.info
vim-7.2-docs.tcz.info vimtutor.tcz.info
and then cat into one file to terminal.
Also added: update -vx. This lists the files from the persistent database if present.
EDIT: improved report code for easier viewing of multiple files
EDIT: fixed misplace "fi" in permission check.
