+<p>
+SQLite is "stand-alone" or "self-contained" in the sense that it
+has very few dependencies. It runs on any operating system, even
+stripped-down bare-bones embedded operating systems. SQLite uses
+no external libraries or interfaces (other than a few standard C-library
+calls described below). The entire SQLite library is
+encapsulated in a <a href="amalgamation.html">single source code file</a> that requires
+no special facilities or tools to build.
+
+</p><p>
+A minimal build of SQLite requires just these routines from the
+standard C library:
+</p><ul>
+<li>memcmp()
+</li><li>memcpy()
+</li><li>memmove()
+</li><li>memset()
+</li><li>strcmp()
+</li><li>strlen()
+</li><li>strncmp()
+</li></ul>
+
+<p>
+Most builds also use the system memory allocation routines:
+</p><ul>
+<li>malloc()
+</li><li>realloc()
+</li><li>free()
+</li></ul>
+<p>But those routines are optional and can be omitted
+using a <a href="compile.html#zero_malloc">compile-time option</a>.
+
+</p><p>
+Default builds of SQLite contain appropriate <a href="vfs.html">VFS objects</a> for talking
+to underlying operating system, and those VFS objects will contain
+operating system calls such as open(), read(), write(), fsync(), and
+so forth. All of these interfaces are readily available on most platforms,
+and custom VFSes can be designed to run SQLite on even the most
+austere embedded devices.
