-# A Couple of env vars are available to effect usage of this eclass
+# A Couple of env vars are available to effect behaviour of this eclass
# These are as follows:
#
-# K_NOSETEXTRAVERSION - if this is set then EXTRAVERSION will not be automatically set within the kernel Makefile
-# K_NOUSENAME - if this is set then EXTRAVERSION will not include the first part of ${PN} in EXTRAVERSION
-# K_PREPATCHED - if the patchset is prepatched (ie: mm-sources, ck-sources, ac-sources) it will use PR (ie: -r5) as the patchset version for
-# - and not use it as a true package revision
-# K_EXTRAEINFO - this is a new-line seperated list of einfo displays in postinst and can be used to carry additional postinst messages
-# K_EXTRAEWARN - same as K_EXTRAEINFO except ewarn's instead of einfo's
-
-# H_SUPPORTEDARCH - this should be a space separated list of ARCH's which can be supported by the headers ebuild
-
-# UNIPATCH_LIST - space delimetered list of patches to be applied to the kernel
-# UNIPATCH_EXCLUDE - an addition var to support exlusion based completely on "<passedstring>*" and not "<passedno#>_*"
-# - this should _NOT_ be used from the ebuild as this is reserved for end users passing excludes from the cli
-# UNIPATCH_DOCS - space delimemeted list of docs to be installed to the doc dir
-# UNIPATCH_STRICTORDER - if this is set places patches into directories of order, so they are applied in the order passed
+# K_NOFIXINSTALL_PATH - some patches (wolk for example) dont like INSTALL_PATH
+# being fixed prior to patching. therefore having this
+# option set disables the command to change this.
