void `addImport`(string `path`);
  Add import path to the global.`path`.
  Parameters:

  string `path` | import to add

string `findDMDConfig`(string `dmdFilePath`);
  Searches for a dmd.conf.
  Parameters:

  string `dmdFilePath` | path to the current DMD executable

  Returns:
  full path to the found dmd.conf, null otherwise.
string `findLDCConfig`(string `ldcFilePath`);
  Searches for a ldc2.conf.
  Parameters:

  string `ldcFilePath` | path to the current LDC executable

  Returns:
  full path to the found ldc2.conf, null otherwise.
string `determineDefaultCompiler`();
  Detect the currently active compiler.
  Returns:
  full path to the executable of the found compiler, null otherwise.
auto `parseImportPathsFromConfig`(string `iniFile`, string `execDir`);
  Parses a dmd.conf or ldc2.conf config file and returns defined import paths.
  Parameters:

  string `iniFile` | iniFile to parse imports from
  string `execDir` | directory of the compiler binary

  Returns:
  forward range of import paths found in `iniFile`
auto `findImportPaths`();
  Finds a dmd.conf and parses it for import paths. This depends on the $DMD environment variable. If $DMD is set to ldmd, it will try to detect and parse a ldc2.conf instead.
  Returns:
  A forward range of normalized import paths.

Module `parseModule`(string `fileName`, string `code` = null);
  Parse a module from a string.
  Parameters:

  string `fileName` | file to parse
  string `code` | text to use instead of opening the file

  Returns:
  the parsed module object
void `fullSemantic`(Module `m`);
  Run full semantic analysis on a module.
string `prettyPrint`(Module `m`);
  Pretty print a module.
  Returns:
  Pretty printed module as string.
