14 This manual is a guide to PSPP internals. Its intended audience is
15 developers who wish to modify or extend PSPP's capabilities. The use
16 of PSPP is documented in a separate manual. @xref{Top, ,
17 Introduction, pspp, PSPP Users Guide}.
19 This manual is both a tutorial and a reference manual for PSPP
20 developers. It is ultimately intended to cover everything that
21 developers who wish to implement new PSPP statistical procedures and
22 other commands should know. It is currently incomplete, partly
23 because existing developers have not yet spent enough time on writing,
24 and partly because the interfaces not yet documented are not yet
25 mature enough to making documenting them worthwhile.
27 PSPP developers should have some familiarity with the basics of PSPP
28 from a user's perspective. This manual attempts to refer to the PSPP
29 user manual's descriptions of concepts that PSPP users should find
30 familiar at the time of their first reference. However, it is
31 probably a good idea to at least skim the PSPP manual before reading
32 this one, if you are not already familiar with PSPP.
