# Introduction to the magic_* subroutines.
#
# The following routines are called after the distfiles have been
# downloaded and extracted. They may inspect the extracted files
# to automatically define some variables in the package Makefile.
#
# The following variables may be used in the magic_* subroutines:
# $distname contains the package name, including the version number.
# $abs_wrkdir is an absolute pathname to the working directory, which
# contains the extracted distfiles. $abs_wrksrc is the absolute pathname
# to a subdirectory of $abs_wrkdir, in which you can usually find the
# package-provided Makefiles or configure scripts.
#
# The following lists may be extended by the magic_* routines and
# will later appear in the package Makefile: @depends and @build_depends
# contain the dependencies of the package, in the form
# "package>=version". @includes is a list of pathnames relative to the
# package path. All these files will be included at the bottom of the
# Makefile. @build_vars is a list of [varname, value] items that contain
# variables that will be defined in the fourth paragraph of the package
# Makefile, where the build configuration takes place. The @extra_vars
# are similar to the @build_vars, but separated by an empty line in the
# Makefile. The @todo items are inserted below the second paragraph in
# the Makefile.
