<Alt

transition to &GAP4;.
With
his help &homalg; became an extendable multi-package project. <
P/>
Max Neunhöffer convinced me
to use his wonderful &IO; package
to
start communicating
with external computer algebra systems. This was
crucial
to remedy the yet missing support
for important rings
in
&GAP;.
Max provided the first piece
of code
to access the computer
algebra system &Singular;. This was the starting point
of the
packages &HomalgToCAS;
and &IO_ForHomalg;, which were further abstracted
by Simon
and myself enabling &homalg;
to communicate
with virtually
any external
(computer algebra) system. <

interface <C>cmaple</C>. <

The basic support

by Simon,
and the support

&Singular; was initiated

contributed the complete support
for &MAGMA;. This formed the
beginning
of the &RingsForHomalg; package. Recently, Daniel added
the support
for &Macaulay2;. <
P/>
My concerns about how
to handle the garbage collection
in the
external computer algebra systems were evaporated
with the idea
of
Thomas Breuer using the so-called <Alt Only=
"Text">weak
pointers</Alt><Alt Only=

in &GAP4;
to keep track
of all the
external objects that became obsolete
for &homalg;. This idea took
shape
in a discussion
with him
and Frank
Lübeck
and finally found
its way into the package &HomalgToCAS;. <
P/>
My gratitude
to all
with whom I worked together
to develop extension
packages
and those who developed their own packages within the
&homalg; project (&see; Appendix <Ref Sect=
"homalg-Project"/>).
Without their contributions the package &homalg; would have remained
a core without a body:
