    3: # To build a single huge source file holding all of SQLite (or at
    4: # least the core components - the test harness, shell, and TCL 
    5: # interface are omitted.) first do
    6: #
    7: #      make target_source
    8: #
    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
   18: # this script:
   19: #
   20: #      tclsh mksqlite3c.tcl

   22: # The amalgamated SQLite code will be written into sqlite3.c
   23: #
   24: 
   25: # Begin by reading the "sqlite3.h" header file.  Extract the version number
   26: # from in this file.  The versioon number is needed to generate the header
   27: # comment of the amalgamation.

   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.
