# The following macros should be defined before this script is
# invoked:
#
# TOP              The toplevel directory of the source tree.  This is the
#                  directory that contains files "VERSION" and "README".
#
# BCC              C Compiler and options for use in building executables that
#                  will run on the platform that is doing the build.
#
# TCC              C Compiler and options for use in building executables that 
#                  will run on the target platform.  This is usually the same
#                  as BCC, unless you are cross-compiling.
#
# THREADLIB        Specify any extra linker options needed to make the library
#                  thread safe
#
# OPTS             Extra compiler command-line options for the TCC compiler
#
# EXE              The suffix to add to executable files.  ".exe" for windows
#                  and "" for Unix.
#
# AR               Tools used to build a static library.
# RANLIB
#
# TCL_FLAGS        Extra compiler options needed for programs that use the
#                  TCL library.
#
# LIBTCL           Linker options needed to link against the TCL library.
#
# READLINE_FLAGS   Compiler options needed for programs that use the
#                  readline() library.
#
# LIBREADLINE      Linker options needed by programs using readline() must
#                  link against.
#
# NAWK             Nawk compatible awk program.  Older (obsolete?) solaris
#                  systems need this to avoid using the original AT&T AWK.
#
# Once the macros above are defined, the rest of this make script will
# build the SQLite library and testing tools.

This directory contains source code to 

    SQLite: An Embeddable SQL Database Engine

To compile the project, first create a directory in which to place
the build products.  It is recommended, but not required, that the
build directory be separate from the source directory.  Cd into the
build directory and then from the build directory run the configure
script found at the root of the source tree.  Then run "make".

For example:

    tar xzf sqlite.tar.gz    ;#  Unpack the source tree into "sqlite"
    ./autogen.sh             ;#  Create the configure script
    configure                ;#  Run the configure script
    mkdir bld                ;#  Build will occur in a sibling directory
    cd bld                   ;#  Change to the build directory
    ../sqlite/configure      ;#  Run the configure script
    make                     ;#  Run the makefile.
    make install             ;#  (Optional) Install the build products

The configure script uses autoconf 2.61 and libtool.  If the configure
script does not work out for you, there is a generic makefile named
"Makefile.linux-gcc" in the top directory of the source tree that you
can copy and edit to suit your needs.  Comments on the generic makefile
