23 # Script : gtkdoc-scan
24 # Description : Extracts declarations of functions, macros, enums, structs
25 # and unions from header files.
27 # It is called with a module name, an optional source directory,
28 # an optional output directory, and the header files to scan.
30 # It outputs all declarations found to a file named
31 # '$MODULE-decl.txt', and the list of decarations to another
32 # file '$MODULE-decl-list.txt'.
34 # This second list file is typically copied to
35 # '$MODULE-sections.txt' and organized into sections ready to
36 # output the SGML pages.
