+
+ * install-mk (MK_VERSION): 20130505
+ * gendirdeps.mk, meta2deps.py, meta2deps.sh: handle $TARGET_SPEC
+ for when $MACHINE isn't enough for objdir distinction.
+ Bring meta2deps.sh closer to par with meta2deps.py.
+
+2013-04-18 Simon J. Gerraty <sjg@bad.crufty.net>
+
+ * meta.stage.mk: set INSTALL to STAGE_INSTALL when making 'all'
+ also if the target 'beforeinstall' exists, make it depend on
+ .dirdep (incase it uses STAGE_INSTALL).
+
+2013-04-17 Simon J. Gerraty <sjg@bad.crufty.net>
+
+ * install-mk (MK_VERSION): 20130401 ;-)
+ * meta.stage.mk (STAGE_INSTALL_SH): add stage-install.sh as
+ wrapper around install(1).
+ * options.mk (OPTION_PREFIX): Allow a prefix other than MK_
+
2013-03-30 Simon J. Gerraty <sjg@bad.crufty.net>
* meta2deps.py (MetaFile.__init__): ensure self.cwd is initialized.

+# NAME:
+# stage-install.sh - wrapper around install
+#
+# SYNOPSIS:
+# stage-install.sh [variable="value"] "args" "dest"
+#
+# DESCRIPTION:
+# This script is a wrapper around the normal install(1).
+# Its role is to add '.dirdep' files to the destination.
+# The variables we might use are:
+#
+# INSTALL
+# Path to actual install(1), default is
+# $REAL_INSTALL
+#
+# OBJDIR
+# Path to the dir where '.dirdep' was generated,
+# default is '.'
+#
+# _DIRDEP
+# Path to actual '.dirdep' file, default is
+# $OBJDIR/.dirdep
+#
+# The "args" and "dest" are passed as is to install(1), and if a
+# '.dirdep' file exists it will be linked or copied to each
+# "file".dirdep placed in "dest" or "dest".dirdep if it happed
+# to be a file rather than a directory.
