It's an Amiga Installer script, and basically it does the following:
(run "wget" (cat "
ftp://ftp.zedonet.com/tp2/turboprint-" #tp ".i586.tgz"))
(complete 25)
(working "unarchive")
(run "xaduntar" (cat "turboprint-" #tp ".i586.tgz T:"))
(delete (cat "turboprint-" #tp ".i586.tgz"))
(complete 50)
(copyfiles
(prompt "Copying printers directory")
(source (cat "T:turboprint-" #tp "/printers"))
(dest "TurboPrint:printers/")
(help @copyfiles-help)
(pattern "#?.tpp")
)
(complete 75)
(copyfiles
(prompt "Copying colors directory")
(source (cat "T:turboprint-" #tp "/colors"))
(dest "TurboPrint:colors/")
(help @copyfiles-help)
(pattern "#?.tpm")
)
Ie. downloads some updated files from an FTP server. By the name of the archive it would seem to be a package for the Intel Pentium architecture. But not having downloaded the 16Mb I can't be sure.
