+# BUSYBOX ALTERNATE CONFIG MINI-HOWTO
+#
+# Busybox can be modified in many different ways. Here's a few ways to do it:
+#
+# (1) Emerge busybox with FEATURES=keepwork so the work directory won't
+#     get erased afterwards. Add a definition like ROOT=/my/root/path to the
+#     start of the line if you're installing to somewhere else than the root
+#     directory. This command will save the default configuration to
+#     ${PORTAGE_CONFIGROOT} (or ${ROOT} if ${PORTAGE_CONFIGROOT} is not
+#     defined), and it will tell you that it has done this. Note the location
+#     where the config file was saved.
+#
+#     FEATURES=keepwork USE=savedconfig emerge busybox
+#
+# (2) Go to the work directory and change the configuration of busybox using its
+#     menuconfig feature.
+#
+#     cd /var/tmp/portage/busybox*/work/busybox-*
+#     make menuconfig
+#
+# (3) Save your configuration to the default location and copy it to the
+#     one of the locations listed in /usr/portage/eclass/savedconfig.eclass
+#
+# (4) Emerge busybox with USE=savedconfig to use the configuration file you
+#     just generated.
+#
+################################################################################
+#
+# (1) Alternatively skip the above steps and simply emerge busybox without
+#     USE=savedconfig.
+#
+# (2) Edit the file it saves by hand. ${ROOT}"/etc/portage/savedconfig/${CATEGORY}/${PF}
+#
+# (3) Remerge busybox as using USE=savedconfig.
