| # there and will not work if they are not found.) There are a few |
| # generated C code files that are also added to the tsrc directory. |

| # the parser are derived from "parse.y" using lemon. And the |
| # "keywordhash.h" files is generated by a program named "mkkeywordhash". |

| # After the "tsrc" directory has been created and populated, run |
| # this script: |
| # |

| ** This file is an amalgamation of many separate C source files from SQLite |
| ** version $VERSION. By combining all the individual C code files into this |
| ** single large file, the entire code can be compiled as a single translation |
| ** unit. This allows many compilers to do optimizations that would not be |
| ** possible if the files were compiled separately. Performance improvements |
| ** of 5% or more are commonly seen when SQLite is compiled as a single |
| ** translation unit. |
| ** |
| ** This file is all you need to compile SQLite. To use SQLite in other |
| ** programs, you need this file and the "sqlite3.h" header file that defines |
| ** the programming interface to the SQLite library. (If you do not have |
| ** the "sqlite3.h" header file at hand, you will find a copy embedded within |
| ** the text of this file. Search for "Begin file sqlite3.h" to find the start |
| ** of the embedded sqlite3.h header file.) Additional code files may be needed |
| ** if you want a wrapper to interface SQLite with your choice of programming |
| ** language. The code for the "sqlite3" command-line shell is also in a |
| ** separate file. This file contains only code for the core SQLite library. |
