Good documentation is essential for users to fully understand any
   software. Several PEAR packages lack documentation or have docs which
   need improvement. Writing documentation
   provides more information about helping out on this front.
  
   Translating documentation is another important task.
   Not only does new documentation need to be translated
   into the existing languages, additional languages are
   welcome. Also, existing translations need to be brought
   up to date because the English versions have been changed.
   Help on how to perform the translation process is in the Revision Tracking
   section of the manual.
