In addition to original PostgreSQL's files followings are added:

- doxygen.list:	Pgpool-II's typedefs extraced by doxygen. Plus manually added typedefs that were not detected by doxygen.
- enums.list:	Pgpool-II's enums manually extracted from source code.
- exclude_files:	files that should not be touched pgindent.
- run_pgindent:	handy script to run pgindent. Should be run at src directory.
- typedefs.list.PostgreSQL:	PostgreSQL's typedefs. To prepare for that doxygen misses some typedefs.
- make_typedefs.list: handy script to generate typedefs.list.

The steps to run pgindent are follows:

1. Add new typedefs to doxygen.list. You can add it to the end of the file.
2. Add new enums to enums.list. You can add it to the end of the file.
3. If necessary update typedefs.list.PostgreSQL by copying PostgreSQL's typedefs.list.
4. Run make_typedefs/list to generate typedefs.list.
5. Run pgindent by using run_pgindent at src directory.
