  The complete SQLite library is about 230KiB statically linked.  By
  omitted unused features, the size of SQLite can be reduced to around
  170KiB.
! The size of Firebird is measured in megabytes.  The size of firebird
! is reported to be shrinking, but it is still roughly 10 times larger than
! SQLite and is never expected to be as lightweight.

  SQLite requires no setup files or other administration.  You just
! call sqlite3_open() with the name of a database filie and it runs.
! Firebird, in contrast, requires that a configuration file be present
! in the working directory and is more complex to initialize.
