QUICK START GUIDE

This CSS3 Font Converter is a shell script that allows developers, using a command line, to convert a set of TTF and OTF fonts into all the other currently used CSS3 @font-face formats (i.e. EOT, SVG, WOFF, WOFF2).
Syntax:

convertFonts.sh <filelist>

For example, if you wanted to convert all the .ttf files in the directory you are in, you could type in the command:

$ convertFonts.sh *.ttf

The fonts will then be converted to the .eot, .woff, and .svg formats. It will also generate a stylesheet, stylesheet.css, that will produce the @font-face rules using The New Bulletproof @Font-Face Syntax.

If you are converting .otf fonts, a .ttf font will be generated first before the other fonts.

FULL COMMAND LINE OPTIONS

Usage: /Users/zhawry/bin/convertFonts.sh [-options] [fontfilelist]

Where: - [fontfilelist] is a space separated list of True Type (.ttf) or Open Type (.otf) fonts.

   - [-options] are one of the following:
   
     --use-font-weight: This option will merge all font-weights and 
     styles under the same font name.  This option will likely crash
     Apple Mobile Safari running under iOS versions less than 4.0.
     Also note that only the first four weights and styles
     will be recognized under IE7 and 8.
     
     --use-font-stretch: This option will merge all condensed and 
     expanded fonts under the same font name as the normal font.
     It is recommended *not* to use this method currently, since at
     the time of this writing, font-stretch is only supported by 
     Firefox => 9 and IE => 9.
     
     --autohint: This option will hint/re-hint fonts (using ttfautohint
     by default, or Adobe Font Development Kit for OpenType if using
     the --autohint=adobe option ). Note that this option will create
     a bunch of files prefixed with 'hinted-'.  Attempting to use this 
     option on files already prefixed with 'hinted-' will result in an 
     error.

  	 --use-font-prefix=xxx: This option will prepend the name of all the
  	 fonts with the string xxx.  This is useful when you are generating
  	 different stylesheets using the converter with the same font 
  	 but with different options.
  
  	 --output=xxx: This option will produce the resultant @font-face
     stylesheet to the file xxx. By default, xxx is set to stylesheet.css
     
     --show-features: Presents the user with a list of OpenType feature 
     tags a font supports which can be used inside a style sheet using 
     the CSS3 font-feature-settings property. The font can be in either 
     be OpenType or TrueType.
     
     --help: This help menu.
