# This package builds the vanilla git kernel by default,

# but it is possible to patch the source without modifying
|
|
# this PKGBUILD.
|
|
#
|
|
# Simply create a directory 'patches' in your PKGBUILD
|
|
# directory and _any_ file (dotfiles excluded) in this
|
|
# folder will be applied to the kernel source.
|
|
#
|
|
# Prefixing the patch file names with dots will obviously
|
|
# excluded them from the patching process.
