## This "library" converts texi-isms into man-isms. It gets included
## by the man page template at the point where texi-isms might start appearing
## and then "emit-man-text" is invoked when all the text has been assembled.
##
## Display the command line prototype,
## based only on the argument processing type.
##
## And run the entire output through "sed" to convert texi-isms
# /bin/sh on Solaris is too horrible for words
