.\" a simple set of macros to provide HTML documents with basic www functionality
.\"
.\" please can someone with more skill at creating macros improve on this

.\"

.\" references.
.\"
.\" some simple html additions to any macro set

.\" CDFTP - if we are processing this on machine \\$1 then we create a

.\" .CDFTP "foobar" "somegnusoftware.tar.gz" \
.\" "ftp://ftp.gnu.org/gnu/somegnusoftware.tar.gz" \
.\" "../../../TARGZ/somegnusoftware.tar.gz"
.\"
.\" meaning if we are on machine foobar then generate an ftp url
.\" to the GNU anonymous ftp server otherwise generate a file url
.\" to a local copy (cdrom maybe)
.\"
.\" Useful when one machine is designated as a cdrom burner and another
.\" designated as an appache server.
.\" The same source for web pages can be burnt onto a CD and also
.\" served across the network. It doesn't solve the problem of one
.\" machine doing both though :-(

.de CDFTP
. sy /bin/rm -f /tmp/tmac.n
. sy /bin/echo ".ds HOSTNAME `hostname --short`" > /tmp/tmac.n

.\" it doesn't make sense to use hyphenation with html, so we turn it off.
