+doc = """USAGE: python /path/to/inputCustomize.py [INPUT] [--dest=OUTPUT] [OPTIONS]
+Use this script to customize one or more Input font files.
+Requires TTX/FontTools: <http://sourceforge.net/projects/fonttools/>
+
+If INPUT is missing, it will customize all fonts in the Current Working Directory.
+If OUTPUT is missing, it will overwrite the INPUT files.
+
+Options:
+    -h, --help              Print this help text, and exit.
+    --lineHeight=<float>    A multiplier for the font's built-in line-height.
+    --fourStyleFamily       Only works when four INPUT files are provided. 
+                            Assigns Regular, Italic, Bold, and Bold Italic names to the 
+                            INPUT fonts in the order provided.
+    --suffix=<string>       Append a suffix to the font names. Takes a string with no spaces.
+    --a=ss                  Swaps alternate single-story 'a' for the default double-story 'a'
+    --g=ss                  Swaps alternate single-story 'g' for the default double-story 'a'
+    --i=serif               Swaps one of the alternate 'i' for the default in Sans/Mono
+        serifs
+        serifs_round
+        topserif
+    --l=serif               Swaps one of the alternate 'l' for the default in Sans/Mono
+        serifs
+        serifs_round
+        topserif
+    --zero=slash            Swaps the slashed zero for the default dotted zero
+           nodot            Swaps a dotless zero for the default dotted zero
+    --asterisk=height       Swaps the mid-height asterisk for the default superscripted asterisk
+    --braces=straight       Swaps tamer straight-sided braces for the default super-curly braces
+
+    Example 1:
+    $ cd /path/to/the/top/level/of/the/fonts/you/want/to/edit
+    $ python /path/to/InputCustomize.py --dest=/path/to/output  --lineHeight=1.5 --suffix=Hack --fourStyleFamily --a=ss --g=ss --i=topserif --l=serifs_round --zero=slash --asterisk=height
+    
+    Example 2:
+    $ cd /path/to/the/top/level/of/the/fonts/you/want/to/edit
+    $ python /path/to/InputCustomize.py InputSans-Regular.ttf InputSans-Italic.ttf InputSans-Bold.ttf InputSerif-Regular.ttf --suffix=Hack --fourStyleFamily
