Controls how the online documentation interface finds a web browser exectuable (either Netscape or Mosaic) to use. The value should be nil or a string .
If the value is nil , LispWorks attempts to find the browser using the value of the environment variable PATH .
If the value is a string, it specifies the directory in which the browser is installed. Typical values are "/usr/bin/" and "/usr/local/bin/" . Note: do not omit the trailing slash.
