/*** NOTE: This config.php file MUST contain only const declarations and no declarations of global variables 
 *   This is due to a number of issues with PHP design where 1) const cannot be used in string interpolation 
 *   and 2) const definitions are not allowed to contain (most) operations and 3) the peculiar way we neeed this 
 *   file in mediawiki as well as in our own endpoint files.

/* *** ADDING another xml tag ***

1) Parsifal.php  for the hooks
2) TexProcessor.php  for the mapping

The place where we want to insert the xml tag content:
  magic-line-identifier-for-inclusion

When we use a preloaded format we must use the correct versions(one for latex, one for pdflatex).
We do so by placing the formats into different format directories and use different environment variables.
