What is my $LM_PATH ? (PHP Question)

I am installing a mailer app, and it is asking me for my $LM_PATH

Here is what the code looks like… I am on a linux machine…

[COLOR=Orange] // Full directory path with trailing slash to ListMessenger directory.
// Examples: Linux /home/vhosts/domain.com/httpdocs/listmessenger/
// Windows C:/websites/domain.com/public_html/listmessenger/
// When using Windows, use forward slashes, not backslashes.
[COLOR=Black]$LM_PATH = [/COLOR][COLOR=Red]"…/";[/COLOR]

thanks guys…
