The build system deduces inter-module dependencies from the symbols required and exported by the modules. This works well, except for some rare cases where the dependency is indirect or hidden. A module might not make use of any function of some other module, but still expect its functionality to be available to GRUB. To solve this, introduce a new file, currently empty, called extra_deps.lst to track these cases manually. This file gets processed in the same way as the automatically generated syminfo.lst, making it possible to inject data into the dependency resolver. Since *.lst files are set to be ignored by git, add an exception for extra_deps.lst. Additionally, introduce a new keyword for the syminfo.lst syntax: "depends" allows specifying a module dependency directly: depends <module> <depdendency>...

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. See the file MAINTAINERS for information about the GRUB maintainers, etc. If you found a security vulnerability in the GRUB please check the SECURITY file to get more information how to properly report this kind of bugs to the maintainers. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
