How can I achieve this? For multiple packages I have this happens:
Application setup launches into configure or build phase, some script creates a file where the creation process can not be located easily asuming that a "#! /bin/sh" as shebang and/or "/bin/sh" as executable somewhere in the file will just work and our build system says "¡No pasarán!"... So I was thinking, Guile is flexible, it should be achievable to have something which wraps itself around the phase and for a new file it just patches in what you throw at it in advance. Of course I'm open for whatever works before we get to this. Examples I can think off my head are the mach buildsystem used by the firefox deriviate palemoon, pike (as far as I know, been some time since I made progress on this one). Thanks -- ng0
