Re: [docbook-apps] XML catalogs on Cygwin

[Michael Smith <smith@xml-doc.org>]

er, my mailer munged the backslashes in my message; everywhere you see a
question mark (or some other weird character) in the command-line
examples, replace it with a backslash...

(and if anybody else on the list happens to be using Mutt in a
Japanese-enabled environment, and can tell me how I might be able to
prevent it from from munging backslashes, I'd appreciate it...)
