#     V 1.1    22.11.1996   Lutz Kettner
#              Project: tools around the CGAL manual writing task.
#              extract, check, HTML conversion.
#     V 1.2    03.12.1996   Lutz Kettner
#              Tools renamed from CGAL to CC. Relates to cc_manual.sty R2.1.

# Analog of the TEXINPUTS environment variable for the cc_extract_html
# program. It should contain a colon-separated list of directories where
# the input files can be found. If this is not set, the default is that
# files are looked for in the current directory. If this is set, then
# directories are searched in the order provided in this variable (so "."
# should be included in the list if some input files are in the current
# directory).
