How, exactly, does siag's help try to invoke lynx or dillo (i.e.
what's the form of the command and what info is passed)? It's
possible that a one-liner shell script could be used as a
command-line proxy for a Macintosh browser such as IE or Netscape,
since such browsers can be instructed at the command line to open
html documents with comands of the form "open -a some_brower.app
some_html_doc.html". Also, if the "open" command is used without the
"-a some_browser.app" option, then "some_html_doc.html" will be
opened by whatever handles .html files by default, which is likely
the person's favorite browser, so maybe the "open" command could be
used in place of the "lynx" command, assuming that siag doesn't need
a terminal based browser.

It's tempting to try "setenv SIAGHELP open". In fact, when I get a
moment, I will.

my theory was that pw was instructed to open documents it couldn't
find, and was therefore opening new documents with the same names as
help documents. Before opening each "help" window, it would ask me
what format to use (.pw, .txt, .html, etc). However, the file you
mentioned, /sw/share/doc/siag/common/siaghelp.html, appears to exist
on my system, so now I'm baffled.

options 1 and 2 seems the most reliable.
Thanks,
