C code based Yet Another GENerator

Scan C source file using the simple pattern matching to capture the elements in the code
Generate text based files using template files
Supported elements are inclusion, local variable, and functions

Available tags in template file

@sourcename@ : it is given as an argument from command line
@date@ : generated date
@incs@ : the list of inclusion statement such as #include <stdio.h>
- @captured@ : the captured raw string
@end-incs@ : the end of incs block
@local-vars@ : the list of static variables
- @captured@ : the captured raw string
- @name@ : variable name
- @dtype@ : variable data type
@end-local-vars@ : the end of local-var bolck
@fncs@ or @fncs0@ : the list of all the functions
- @captured@ : the captured raw string
- @name@ : the function name
- @rtype@ : the return data type of the function
