# Some versions of col need -x to keep them from converting spaces to tabs;
# some versions of col don't do the conversion by default and don't
# recognize the option.  Sigh.

# Use the "cat" GUIDECMD if nroff and/or tbl and/or col are not installed
# Not appropriate for creating Guidebook.txt.

# Guidebook.tex is the same as Guidebook.mn but formatted with LaTeX.
# - The invocation command for LaTeX may vary in different installations.
# - To print Guidebook.dvi you need to use a suitable dvi-driver.
# - LaTeX needs to be run twice; second pass uses Guidebook.aux made by first.
