bootstrap
1. <operating system> (From "to pull oneself up by one's
bootstraps") To load and initialise the {operating system} on
a computer. Normally abbreviated to "{boot}".
See {bootstrap loader}.
2. <compiler> (From "to pull oneself up by one's bootstraps")
to use a {compiler} to compile itself.
The usual process is to write an {interpreter} for a language,
L, in an existing language, M. The compiler is then written
in L and the interpreter is used to run it. This produces an
{executable} for compiling programs in L from the source of
the compiler in L.
This technique is often used to verify the correctness of a
compiler. It was first used in the {LISP} community.
