/*
  Very simple C program.

   Compile:
     gcc -o simplesqlite3 simplesqlite3.c  -Wall -W -O2 -Wl,-R/usr/local/lib -lsqlite3
  
   Note sqlite3 shared library, by default, installs in /usr/local/lib. 
   The compile command above will directly link the full path of 
   this library into this program.
