// Script Function:
// Allow modification of environmental path directly from Inno Setup installers
//
// Instructions:
// Copy modpath.iss to the same directory as your setup script
//
// Add this statement to your [Setup] section
// ChangesEnvironment=true
//
// Add this statement to your [Tasks] section
// You can change the Description or Flags
// You can change the Name, but it must match the ModPathName setting below
// Name: modifypath; Description: &Add application directory to your environmental path; Flags: unchecked
//
// Add the following to the end of your [Code] section
// ModPathName defines the name of the task defined above
// ModPathType defines whether the 'user' or 'system' path will be modified;
// this will default to user if anything other than system is set
// setArrayLength must specify the total number of dirs to be added
// Result[0] contains first directory, Result[1] contains second, etc.
// const
// ModPathName = 'modifypath';
// ModPathType = 'user';
//
// function ModPathDir(): TArrayOfString;
// begin
// setArrayLength(Result, 1);
// Result[0] := ExpandConstant('{app}');
