# Documentation for this script. This may be output to stderr
# if the script is invoked incorrectly.
set ::USAGE_MESSAGE {
This Tcl script is used to test the various compile time options 
available for omitting code (the SQLITE_OMIT_xxx options). It
should be invoked as follows:

    <script> ?-makefile PATH-TO-MAKEFILE?

The default value for ::MAKEFILE is "../Makefile.linux.gcc".

This script builds the testfixture program and runs the SQLite test suite
once with each SQLITE_OMIT_ option defined and then once with all options
defined together. Each run is performed in a seperate directory created
as a sub-directory of the current directory by the script. The output
of the build is saved in <sub-directory>/build.log. The output of the
test-suite is saved in <sub-directory>/test.log.

Almost any SQLite makefile (except those generated by configure - see below)
should work. The following properties are required:

  * The makefile should support the "testfixture" target.
  * The makefile should support the "test" target.
  * The makefile should support the variable "OPTS" as a way to pass
    options from the make command line to lemon and the C compiler.

More precisely, the following two invocations must be supported:

  make -f $::MAKEFILE testfixture OPTS="-DSQLITE_OMIT_ALTERTABLE=1"
  make -f $::MAKEFILE test

Makefiles generated by the sqlite configure program cannot be used as
they do not respect the OPTS variable.

# Build a testfixture executable and run quick.test using it. The first
# parameter is the name of the directory to create and use to run the
# test in. The second parameter is a list of OMIT symbols to define
# when doing so. For example:
