PMPPKG file extension

The PMPPKG file extension is associated with Pegasus Mail. You can now attach a file with the extension "*.PMPPKG" (short for "Pegasus Mail Preferences Package") to any message, and Pegasus Mail will handle it in a special fashion. If the recipient opens or double-clicks any attachment with that extension, Pegasus Mail will assume that it is a preferences package and will offer the user the option of merging the preferences settings it contains with his/her current preference settings. The .PMPPKG file is simply a modified version of PMAIL.INI, containing any of the sections in PMAIL.INI, each section with one or more preference setting you want to alter (so, you don't have to include the whole section - you can just change one or two items): you can use command substitutions in any field; can use "x" placeholders in any of the integer block fields to preserve the current value at that position, and can use "-" in the "Default settings values" field to preserve the value at that position in the string. .PMPPKG handling is hard-wired into the program, but can be overridden by adding entries into FILETYPE.PM (either manually or using the "Viewers" preferences page).
