//
// where $font is a string pointing to the font file

// Purpose:
//
// Reads a font and stores all information related to the font name and
// copyright in an associative array
//
// Returns:
//
// $array["copy"] = copyright information
// $array["font family"] = font family information
// $array["font subfamily"] = font subfamily name
// $array["id"] = unique font identification
// $array["name"] = full font name
// $array["version"] = font version
// $array["postscript name"] = postscript name for the font
// $array["tm"] = trademark information
// $array["manufacturer"] = font manufacturer name
// $array["designer"] = font designer name
// $array["description"] = font description
// $array["vendor url"] = vendor url
// $array["designer url"] = designer url
// $array["license"] = the terms under which the font may be used
// $array["license url"] = the url pointing to information about the font license
// $array["sample text"] = sample text included with the font for preview displays
// $array["platform"] = platform the font was designed under
//
// or
//
// returns boolean false if name tag can't be found, if the file
// doesn't exist, or if the magic number is not valid.
