 | The header files in this directory are the only ones that should ever be | 
 | included by an embedder of PDFium.  If there arises a need for functionality | 
 | beyond what is present here, then a new API must be added here to provide it. | 
 |  | 
 | Documentation for the API is within the headers. Start by reading fpdfview.h. | 
 |  | 
 | These header files must be entirely contained in this directory; they must | 
 | never include other header files from outside of it. | 
 |  | 
 | These files must compile cleanly without warnings on both C and C++ compilers. | 
 |  | 
 | Changes to these files must be carefully considered to avoid breaking | 
 | compatibility. |
