4 # least the core components - the test harness, shell, and TCL | |
5 # interface are omitted.) first do | |
6 # | |
7 # make target_source | |

9 # The make target above moves all of the source code files into | |
10 # a subdirectory named "tsrc". (This script expects to find the files | |
11 # there and will not work if they are not found.) There are a few | |
12 # generated C code files that are also added to the tsrc directory. | |
13 # For example, the "parse.c" and "parse.h" files to implement the | |
14 # the parser are derived from "parse.y" using lemon. And the | |
15 # "keywordhash.h" files is generated by a program named "mkkeywordhash". | |
16 # | |
17 # After the "tsrc" directory has been created and populated, run | |

59 ** This file is an amalgamation of many separate C source files from SQLite | |
60 ** version $VERSION. By combining all the individual C code files into this | |
61 ** single large file, the entire code can be compiled as a single translation | |
62 ** unit. This allows many compilers to do optimizations that would not be | |
63 ** possible if the files were compiled separately. Performance improvements | |
64 ** of 5% or more are commonly seen when SQLite is compiled as a single | |
65 ** translation unit. | |
66 ** | |
67 ** This file is all you need to compile SQLite. To use SQLite in other | |
68 ** programs, you need this file and the "sqlite3.h" header file that defines | |
69 ** the programming interface to the SQLite library. (If you do not have | |
70 ** the "sqlite3.h" header file at hand, you will find a copy embedded within | |
71 ** the text of this file. Search for "Begin file sqlite3.h" to find the start | |
72 ** of the embedded sqlite3.h header file.) Additional code files may be needed | |
73 ** if you want a wrapper to interface SQLite with your choice of programming | |
74 ** language. The code for the "sqlite3" command-line shell is also in a | |
75 ** separate file. This file contains only code for the core SQLite library. | |
