A-line is a Mac-hosted build system for Mac software projects, currently using the MPW Shell, Perl, and dmake. Projects are defined using various control files that are easily created or edited by humans or generated by programs. A-line converts these into files into makefile fragments which are included by a master makefile which is used for all projects. Dependency tracking (within and across projects) is automatic.
A-line is designed to handle complex, multi-project programs (e.g. those with custom LDEFs, etc.). Sharing libraries among multiple applications is easy.
