### XXX --- Building sys.bib (Utah only)
###
### We want to use the Flux sys.bib file but we don't want to 
### distribute it.  Rather than just editing sys.bib by hand,
### we generate it automatically using aux2bib which extracts
### just the bits we need out of the Flux sys.bib into a local 
### copy of sys.bib.  The command to do this is in yoru build tree:
###
###   BIBINPUTS=/n/fast/usr/lsrc/flux/doc: \
###   BSTINPUTS=/home/reid/local/bibtools: \
###   /home/reid/local/bin/aux2bib -c oskit.aux
###
### and then copy it into your source tree:
###
###   cp references.bib ../../oskit/doc/sys.bib

###
### XXX --- Notable notes about the WWW version:
###
### + `make oskit-www.html' builds the WWW version of the document.  This is
###   *not* done by `make all'.
###
### + To install the WWW version somewhere, do: cp *.html *.css *.gif dest-dir
