## Customized version of db2html to make it easier to use alternate
## stylesheets.  Some versions of db2html support a '-d' option to
## specify this, but not all.  We'll explicitly specify that here.

## The DocBook installations behave differently for the various Linux
## distributions.  Try to make some sense out of it all....
##
## $LINUXDIST holds the name of the distribution
## $JADETAG adds "/#html" to the stylesheet-specification in the Jade
##          command line (see comments below), if necessary for that dist.
