TAlh On-Line Help

TAlh uses an external web-browser to display on-line help.
The TAlh on-line help system consists of a set of html files, one of which provides an index.
The help system is accessed from the Help >> TAlh Help  menu if the environment variable TALH_BROWSER contains a command for starting a web-browser on the computer which runs TAlh.

By default, TAlh loads help files from the TRIUMF controls group's web site via the URL  http://isacwserv.triumf.ca/epics/TAlh/html/index.html.

This URL can be overridden with the command line parameter --helpurl.
