+# @BLURB: functions and environment variables used to set up dirs, paths, names in ebuilds
+# @DESCRIPTION:
+# The netbsd eclass contains a suite of functions and environment variables used to setup many
+# paths, directory names, and other things in Gentoo/NetBSD. I try to be as much explicit as I
+# can. Read comments to understand how does the function work and what it does.
+
+# Source directory.
+# I wanted to let end-user the possiblity to set where he wants to push NetBSD sources on his machine. 
+# It can now be achieved with a variable which have to be set in make.conf: NETBSD_SRC_DIR.
+# ex: NETBSD_SRC_DIR="/usr" or "/docs/netbsd-5.0"
+# Default, if not set, is "/usr"
+if [ -z ${NETBSD_SRC_DIR} ]; then
+  NETBSD_SRC_DIR="/usr"
+fi
+
+# CVS directory MUST ALWAYS be "src"
+# that's why we set it as readonly.
+readonly NETBSD_CVS_DIR="src"
+
+# This is the global path of where sources are pushed on user's machine.
+# We'll need it later.
+NETBSD_SRC_DIR="${NETBSD_SRC_DIR}/${NETBSD_CVS_DIR}"
+export NETBSD_SRC_DIR
+
+# Tools directory.
+# Default, if not set, is tooldir.NetBSD-5.0-i386
+# Later, we can think about USE flags which would cross-compile
+# tools and system in another directory, using ROOT option,
+# in order to build the system for a different CPU architecture.
+if [ -z ${NETBSD_SRC_TOOLDIR} ]; then

+# @FUNCTION: netbsd_create_dirs
+# @USAGE: <pattern>
+# @DESCRIPTION:
+# This function is used before invoking "make install". A common problem, while invoking "make install",
+# is that make doesn't create directories in DESTDIR before installing files.
+# I've noticed that NetBSD system directory hierarchy is described in /etc/mtree so we just need
+# to use this file to construct the hierarchy of the directory we want to build inside our DESTDIR.
+# For example, if I want to create /usr/share directory hierarchy, I just need to use the function
+# like this: netbsd_create_dirs usr/share and it will create every directories and sub-directories
+# in DESTDIR (which is ${D}).
