+ message, in relation to pre-install hooks.

+
+ Correct scheduling of new prerequisites when upgrading.
+
+ * src/pkgdeps.cpp (pkgXmlDocument::ResolveDependencies):
+ [ACTION_UPGRADE && ACTION_PRIMARY]: Don't exclude scheduling for this

+ ...to acquire any user specified version bounds, check that they can
+ be honoured, before scheduling any action; delegate diagnostics to...

+ Don't report failed downloads in respect of virtual packages.
+

+
+2012-03-05 Keith Marshall <keithmarshall@users.sourceforge.net>

+
+ Fix ill-advised optimisation in $APPROOT environment lookup.
+
+ * src/rites.c (approot_path): Don't save result of getenv() lookup
+ across calls; the environment may have been moved in the interim,
+ making the original result invalid on any subsequent call. Also,
+ prefer MS-Windows style (with backslashes) for default.

+ * src/sysroot.cpp (pkgPutEnv): Implement it.
+ (pkgXmlDocument::LoadSystemMap): Use it to add $SUBSYSTEM_SYSROOT path
+ specifications to the environment, for each named subsystem associated
+ with the active system map.
+
+ * src/pkgexec.cpp (pkgActionItem::Execute): Invoke pkgPutEnv() prior
+ to processing of each package install, upgrade, or remove action, so
+ as to update environment variable $SYSROOT to represent the sysroot
+ path for each package processed, during execution of script hooks.
+
+2012-02-17 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Implement hooks to support lua scripting interface.
+
+ * Makefile.in (LIBS): Add -llua.
+
+ * src/pkgbase.h (pkgXmlNode::InvokeScript): New method; declare it
+ as private, and provide overloaded public inline API implementation.
+ (pkgXmlNode::DispatchScript): New private method; declare it.
+
+ * src/pkgexec.cpp (pkgXmlNode::InvokeScript): Implement it.
+ (pkgXmlNode::DispatchScript): Likewise; it directs InvokeScript to...
