## HACK: stuff to avoid making the print docs if installing the
## tools to do so is impractical / too difficult
##-------------------------------------------------------------

# Comment out the next line to skip building print docs.  The default
# is not to skip building print docs.  Note, after changing it
# you of course need to re-run configure to make it take effect.
BUILD_ALL_DOCS=no
