v2Version 2 Compatibility feature Revision : 2.12Kristoffer H. Rosekris@diku.dkComputer Science, University of Copenhagen, Universitetsparken 1, DK–2100 København Ø

3 This option provides backwards compatibility with -pic version 2: diagrams written according to the ``Typesetting diagrams with -pic: User's Manual'' [#!R92:TypesettingDXUM!#] should typeset correctly with this option loaded

There are a few exceptions: the features described in §??[unsupported] below are not provided because they are not as useful as the author originally thought and thus virtually never used. And one extra command is provided to speed up typesetting of documents with -pic version 2 diagrams by allowing the new compilation functionality on old diagrams.

The remaining sections list all the obsolete commands and suggest ways to achieve the same things using -pic , , without the use of this option. They are grouped as to what part of -pic replaces them; the compilation command is described last.

: ``version 2'' is meant to cover all public releases of -pic in 1991 and 1992, , version 1.40 and versions 2.1 through 2.6. The published manual cited above (for version 2.6) is the reference in case of variations between these versions, and only things documented in that manual will be supported by this option!
