What would you like to do?
Tired of dealing with trying to get bold and/or italicized fonts out of iOS given only the font name? This should help.

*
* For example:
*
* [UIFont fontForFamilyName: @"Helvetica" withAttributes: PKFontBold] ==> "Helvetica-Bold"
*
* In addition, if the font name has the word "Bold" or "Italic" (or both), the attributes will
* be used as well, so:
*
* [UIFont fontForFamilyName: @"Helvetica Bold" withAttributes: PKFontNormal] ==> "Helvetica-Bold"
*
* If a font does not support the desired attributes, the nearest rendition is used. In this
* case if a font supports bold but not italic, and we request a bold, italic font, the result
* will be a bold font instead. Likewise, the reverse is true -- if a font only supports italic,
* and we request a bold, italic font, we'll get italic back instead.
*
* For fonts not supported by the mapping matrix, the original font name is returned (minus the
* "Bold" and "Italic" attributes). This is used to support "Symbol" and other fonts with only
* one style.

So, Git was mangling the filetypes. The first file is the header; the second is the module. Use the filenames in the first comment line.
