Test a. Copy INDEX.TST to INDEX. b. Run tib test.tex This uses INDEX and should create a TeX file. (If you get a "INDEX not up to date" message when you test tib, it is because tib is comparing the last modify dates of test.ref and INDEX (with chkindex). Just put INDEX in and out of a text editor (touch) to give it a new date.) Run (plain) TeX on the output file as usual. c. Run tiblook Enter derham when it asks for you to enter something. This also uses INDEX. d. Run tiblist test.ref Run plain TeX on the output. e. Run tibdex test.ref The output of tibdex is a new INDEX which should be identical to INDEX.TST. f. If everything works, the directory can be discarded.
