+"""Pycpdf: a python interface to cpdf.
 
+Before using the library, you must load the libpycpdf and libcpdf DLLs. This is
+achieved with the pycpdf.loadDLL function, given the filename or full path of
+the libpycpdf DLL.  On Windows, you may have to call os.add_dll_directory
+first. On MacOS, you may need to give the full path, and you may need to
+install libcpdf.so in a standard location /usr/local/lib/, or use the
+install_name_tool command to tell libpycpdf.so where to find libcpdf.so.
+
+A 'range' is a list of integers specifying page numbers.
+
+Text arguments and results are in UTF8.
+
+Any function may raise the exception CPDFError, carrying a string describing
+the error.
