xglyph is a program which demonstrates the capabilities of the t1lib library. It allows the user to view an arbitrary character or string rendered in the various ways pgossible with the library. By default, it writes a log file named t1lib.log in the current directory.

If invoked with no arguments, it will attempt to read the global configuration file and font database. It will also accept any number of filenames on the command line, in which case these are treated as font files to be loaded instead of the default font database.
