 # To build a single huge source file holding all of SQLite (or at
 # least the core components - the test harness, shell, and TCL 
 # interface are omitted.) first do
 #
 #      make target_source
 #
 # The make target above moves all of the source code files into
 # a subdirectory named "tsrc".  (This script expects to find the files
 # 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.
 # For example, the "parse.c" and "parse.h" files to implement the
 # 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:
 #
 #      tclsh mksqlite3c.tcl
 #
 # The amalgamated SQLite code will be written into sqlite3.c
 #
 
 # Begin by reading the "sqlite3.h" header file.  Extract the version number
-# from in this file.  The versioon number is needed to generate the header
+# from in this file.  The version number is needed to generate the header
 # comment of the amalgamation.

 ** 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.
