[pacman-dev] Handling splitpkg overrides in scripts
This is the start of what will be a makepkg test suite. It shows a (somewhat robust?) method of parsing splitpkg overrides so will be of use when updating db-scripts to handle splitpkg's with different arch/pkgrel/pkgver's (which can be overrided in pacman-git now). It extracts the "package_foo()" function with a sed statements that assumes that it starts at the start of the line and the closing "}" is the only thing on its line (could be made more robust...). Then is extracts the various variables using a grep. It can handle the following syntax: foo=1 foo=STRING foo="ABC DEF" for=('a' 'b' \ 'c' ) which is basically everything... Any comments on how to improve this are welcome.
