# 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 this "Makefile.in" and the
#                  "configure.in" script.
#
# BCC              C Compiler and options for use in building executables that
#                  will run on the platform that is doing the build.
#
# USLEEP           If the target operating system supports the "usleep()" system
#                  call, then define the HAVE_USLEEP macro for all C modules.
#
# THREADSAFE       If you want the SQLite library to be safe for use within a 
#                  multi-threaded program, then define the following macro
#                  appropriately:
#
# THREADLIB        Specify any extra linker options needed to make the library
#                  thread safe
#
# OPTS             Extra compiler command-line options.
#
# EXE              The suffix to add to executable files.  ".exe" for windows
#                  and "" for Unix.
#
# 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.
#
# 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.
#
# ENCODING         "UTF8" or "ISO8859"
#
# Once the macros above are defined, the rest of this make script will
# build the SQLite library and testing tools.
