1) Download tw.tgz from this page. 2) Extract it anywhere; this is not (typically) where it'll run from. I use $home/src/cmd/tw. 3) Read the mkfile to make sure the install path targets make sense for you. 4) From within the directory you extracted it to, run 'mk install'. Requirements: • Plan 9. • datefmt; see http://9p.io/sources/contrib/anothy/src/cmd/datefmt.c • Highly recommended: a webfs patched to handle modern TLS.
