  1. Run `latex` on `physconst.dtx` to create the `.pdf` file. e.g. 
`xelatex physconst.pdf`.
  1. Run `makeindex` to create the index, e.g. 
`makeindex -s gind.ist -o physconst.ind physconst.idx`.
  1. Run `makeindex` to create the change log, e.g. 
`makeindex -s gglo.ist -o physconst.gls physconst.glo`.
