Yes -- because of the Mac's non-cli oriented nature, droplets are 
especially useful. 

Back when I was bugging you about changing the default BNDLs, I 
posted some examples of trying to make a generic framework for
this sort of thing, which included recursive expansion of 
dropped folders/disks/directories, filtering on file types or
names, and progress bars and prompts. One example was a file-typer
utility which took it's destination type from it's sys.argv[0] name: 
named "-->CARO" , it makes Acrobat Reader the Creator, renamed 
"-->vgrd" it makes them into PostScript textfiles, and renamed
"-->MOSS" it makes Netscape the owner. ( Perhaps an improved
version would use file extensions and/or Internet Config to do 
multiple conversions  .PDF-->CARO, .HTML->MOSS, .PS->vgrd so 
you could update a whole folder or diskful of files with one drop.)


If you're interested in an example, I'll dig back and see if this
has been completely updated for 1.5.1 .
