#  A pbxproj file is an OpenStep format plist
#  {} represents dictionary of key=value pairs delimited by ;
#  () represents list of values delimited by ,
#  file starts with a comment specifying the character type
#  // !$*UTF8*$!

#  when adding a file to a project, create the PBXFileReference
#  add the PBXFileReference's guid to a group
#  create a PBXBuildFile with the PBXFileReference's guid
#  add the PBXBuildFile to the appropriate build phase

#  when adding a header search path add
#  HEADER_SEARCH_PATHS = "path/**";
#  to each XCBuildConfiguration object

#  Xcode4 will read either a OpenStep or XML plist.
#  this script uses `plutil` to validate, read and write
#  the pbxproj file.  Plutil is available in OS X 10.2 and higher
#  Plutil can't write OpenStep plists, so I save as XML
