3.1 Input Format to gperf

You can control the input keyfile format by varying certain command-line arguments, in particular the `-t' option. The input's appearance is similar to GNU utilities flex and bison (or UNIX utilities lex and yacc). Here's an outline of the general format:

 
declarations
%%
keywords
%%
functions

Unlike flex or bison, all sections of gperf's input are optional. The following sections describe the input format for each section.

3.1.1 struct Declarations and C Code Inclusion  
3.1.2 Format for Keyword Entries  
3.1.3 Including Additional C Functions
