Uuencode/uudecode are not universally available. If the ditroff input file is in an 8-bit character set, it is unmailable via some mail transport software. Likewise for 8-bit output, hence the desire to restrict the output to a 7-bit character set. The 'd' and 'i' in ditroff atnd for "device" and "independent", respectively. Ditroff output is *not* tailored to any particular device. The ditroff output can be interpreted by postprocessors for specific devices. The same cannot necessarily be said of other text procssors (perhaps including groff). Postprocessor output *is* tailored to a specific device, hence is not suitable for widespread distibution. Also, note that some of these device-specific output formats (such as PostScript) are both extremely verbose (more so than ditroff output) and may include 8-bit characters. -- Bruce Lilly blilly!balilly!bruce@sonyd1.Broadcast.Sony.COM
