I'm grateful to the following people
for their influence, knowing or not,
on the design of &SCons;:
First, as the original author of &Cons;, Bob did the real heavy
lifting of creating the underlying model for dependency management
and software construction, as well as implementing it in Perl.
During the first years of &Cons;' existence, Bob did a skillful
job of integrating input and code from the first users, and
consequently is a source of practical wisdom and insight into the
problems of real-world software construction. His continuing
advice has been invaluable.
<term>The &SCons; Development Team</term>
A big round of thanks go to those brave souls who have
gotten in on the ground floor:
through their general knowledge of software build issues in general
Python in particular,
have made &SCons; what it is today.
<term>The &Cons; Community</term>
The real-world build problems that the users of &Cons;
share on the <command>cons-discuss</command> mailing list
have informed much of the thinking that
has gone into the &SCons; design.
the current maintainer of &Cons;,
has been a very steady influence.
I've also picked up valuable insight from
and Greg Spencer.
Peter has indirectly
influenced two aspects of the &SCons; design:
Miller's influential paper
<citetitle>Recursive Make Considered Harmful</citetitle>
was what led me, indirectly, to my involvement with &Cons;
in the first place.
Experimenting with the single-Makefile approach he describes in
<citetitle>RMCH</citetitle> led me to conclude that while it worked
as advertised, it was not an extensible scheme. This solidified
my frustration with Make and led me to try &Cons;, which at its
core shares the single-process, universal-DAG model of the "RMCH"
The testing framework that Miller created for his
Aegis change management system
changed the way I approach software development
by providing a framework for rigorous, repeatable
testing during development.
It was my success at using Aegis for personal projects
that led me to begin my involvement with &Cons;
by creating the <command>cons-test</command> regression suite.
An experienced Python programmer,
Stuart provided valuable advice and insight
into some of the more useful Python idioms at my disposal
during the original <literal>ScCons</literal>; design
for the Software Carpentry contest.
I don't know which came first,
the first-round Software Carpentry contest entry
or the tool itself,
but Gary's design for &Makepp;
showed me that it is possible to marry
the strengths of &Cons;-like dependency management
with backwards compatibility for &Makefile;s.
Striving to support both
&Makefile; compatibility and
a native Python interface
cleaned up the &SCons; design immeasurably
by factoring out the common elements
into the Build Engine.
