The settings that you use to tell the launcher what to do all reside within the [Launch] ini section, and are as follows. All are optional.

There are several substitution tokens that may be used within any of the settings requiring a path.

Launched application related tokens are %appdrive%, e.g. H:, %appdir%, e.g. H:\Portables\Firefox, and %appname%, e.g. Firefox. These are of use primarily as a way to create a generic configuration file, such as using %appname%.exe within the Path setting as a way to tie the to-be-launched application's filename to the name of the configuration file, rather than "hard coding" it to the actual name of the application.

Launcher related tokens are %launchdrive%, %launchdir%, and %launchname%. These are of use when the launched application is on a drive that is different from the launcher and the other JauntePE related files used to portably run the application, such as the application's portable registry. For example, if Path is set to %System%\%appname%.exe, but the launcher and JauntePE runtime are located on a portable drive, then %launchdrive% may be used within the JPERuntime setting to portably locate the JauntePE runtime to use without having to resort to use of a relative path.

File system related tokens are %ProgramFiles%, e.g. C:\Program·Files, %System%, e.g. C:\WINNT\system32, and %Windows%, e.g. C:\Windows. These are of use primarily as a way to portably locate "system" applications, such as MS Notepad or MS Office.

And environment variable names enclosed within percent signs may be used as well, such as %ComputerName% or %UserName%. You are responsible for ensuring that the environment variable is available on all versions of Windows on which the launch ini will be used.

There is also a special %jauntePE% substitution token that becomes valid if the JauntePE application itself is 1) running, and 2) the JauntePE.ini is found in the Toolbox subdirectory, and 3) the [GeneralSettings] JPEDLLPath value is set. It's primary purpose is for use within the JPERuntime setting as a portable way to point to the jauntePE runtime dll to be used. The value of the token is the full path as given by the JPEDLLPath relative to the JauntePE.ini's directory, e.g., E:\JauntePE\Runtime\jauntePE\def.

If you specify any relative paths they are taken to be relative to the directory containing the launch ini. Full paths are allowed as well.
