 2.2 Custom Functions
 ====================
 
 Readline provides many functions for manipulating the text of the line,
 but it isn't possible to anticipate the needs of all programs.  This
 section describes the various functions and variables defined within
 the Readline library which allow a user program to add customized
 functionality to Readline.
 
    Before declaring any functions that customize Readline's behavior, or
 using any functionality Readline provides in other code, an application
 writer should include the file `<readline/readline.h>' in any file that
 uses Readline's features.  Since some of the definitions in
 `readline.h' use the `stdio' library, the file `<stdio.h>' should be
 included before `readline.h'.
 
    `readline.h' defines a C preprocessor variable that should be
 treated as an integer, `RL_READLINE_VERSION', which may be used to
 conditionally compile application code depending on the installed
 Readline version.  The value is a hexadecimal encoding of the major and
 minor version numbers of the library, of the form 0xMMMM.  MM is the
 two-digit major version number; MM is the two-digit minor version
 number.  For Readline 4.2, for example, the value of
 `RL_READLINE_VERSION' would be `0x0402'.
