Bullet Is...

 Bullet/2 is a thread-safe, multi-process capable database engine toolkit for
 OS/2.  It provides pre-built and tested access methods to data and index
 files for application programmers.  It is not an end-user Database Management
 System (DBMS), but it is a tool that could be used to develop one.  Bullet is
 compact, efficient, and  very fast.  It can be configured to use custom
 key-build, user sort-compare, and expression-parser routines to extend the
 built-in functionality.  All OS API calls made by Bullet can be replaced with
 custom calls written in C, using most any compiler language.

 The standard data format is DBF (dBASE 3+ and later).  The supported memo
 format is DBT (dBASE 4 and later).  Index-only support can be enabled and with
 this any data file format may be used (the data maintained by the programmer
 then).  Also, the DBF standard may be extended by using binary field values
 and fields larger than 255 bytes.  Index files are NLS-compatible and use an
 efficient b-tree structure.  Files may be any size supported by the OS, up to
 4GB.  Up to 1024 files may be opened and in use by any one process, with any
 number of processes active.

 The Bullet API consists of a wide assortment of routines, from low-level OS
 calls to high-level transaction-list routines that can process hundreds of
 files per transaction, with roll-back on error.  Network/multi-user
 support is included, and makes use of operating system features such as
 atomic re-locking, and shared locks that allow other processes read-access
 to locked files.

 Also available are Bullet/X, for DOS 32-bit compilers and extenders;
 Bullet/95, for Win32 (Win95 and NT) and Win32s (Win31), and Bullet/REXX.
 Bullet for 16-bit compilers is also available.
