+
+2012-09-10 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Move guimain.cpp out of the way.
+
+ * src/guimain.cpp: Rename file as...
+ * src/guistub.cpp: ...this; we want to keep current features for now,
+ but to use the guimain.cpp name for main GUI application development.
+ * Makefile.in: Adjust references accordingly.
+
+2012-09-09 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Fix typo, and update licensing terms for embedded getopt.c
+
+ * src/getopt.c: Incorporate MIT/X style licence; update copyright

+
+2012-09-03 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Correct omission from copyright notice.
+

+
+ Remap Mercurial subrepository reference via local hg-git clone.

+
+2012-08-03 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ More code refactoring, to facilitate GUI implementation.
+
+ * src/clistub.c (AppPathNameW): Factor out; relocate to...
+ * src/approot.c: ...this new file; it reproduces the original

+ the executable path as the first child of the APPROOT prefix. Note
+ also, that no longer terminates APPROOT with a trailing backslash.
+
+ * src/approot.h: New file; it trivially declares the prototype for...

+
+ * src/clistub.c (main): Adapt usage of AppPathNameW(), to reinstate
+ trailing backslash on assignment to APPROOT environment variable.

+
+2012-07-13 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Disable globbing of command line arguments.
+
+ * src/clistub.c (_CRT_glob): Define and initialise to zero; we don't
+ need globbing, and it may cause case transliteration of case-sensitive

+2012-04-30 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Correct sequence of installation/removal progress reporting.
+
+ * src/pkgunst.cpp (pkgRemove): Delay output of "removing package ..."
+ message, until after pre-remove hooks have run; this ensures that any
+ output from the pre-remove hook scripts appears in correct sequence.
+
+ * src/pkginst.cpp (pkgInstall): Likewise, for "installing package ..."
+ message, in relation to pre-install hooks.
+
+2012-04-26 Keith Marshall <keithmarshall@users.sourceforge.net>

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

+ a delegated primary requirement of a meta-package.
+
+2012-04-15 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Don't require subsystem within user specified version bounds.
+
+ * src/pkgdeps.cpp (pkgActionItem::ApplyBounds): Automatically consider

+
+2012-04-09 Charles Wilson <mingw@cwilson.fastmail.fm>
+
+ Fix missing include.

+
+ Don't report failed downloads in respect of virtual packages.
+
+ * src/pkginet.cpp (pkgActionItem::DownloadArchiveFiles): Clear...
+ [ACTION_DOWNLOAD]: ...this status flag for any package identified as
+ a meta-package; this corrects a further regression introduced with the
+ 2011-11-09 update, whereby pending download requests for such virtual

+
+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

+ failure, rather than only the path relative to $APPROOT.
+
+2012-02-20 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Propagate sysroot path settings to scripts via the environment.
+
+ * src/pkgbase.h (PKG_PUTENV_FLAGS_MASK): New constant; it maps...
+ (PKG_PUTENV_DIRSEP_MSW, PKG_PUTENV_DIRSEP_POSIX): ...these flags...

+ path for each package processed, during execution of script hooks.
+
+2012-02-17 Keith Marshall <keithmarshall@users.sourceforge.net>

+
+2011-11-09 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Avoid unnecessary downloads for already installed packages.
+

+ on completion, or when not required due to pre-existing local copy.
+
+ * src/climain.cpp (pkgActionItem::GetSourceArchive): Must always be
+ prepared to download the associated archive; enable ACTION_DOWNLOAD.
+
+ * src/pkgexec.cpp (pkgActionItem::Schedule) [OPTION_REINSTALL]:
+ May need to download the archive, even when the requested package was
+ previously installed; schedule ACTION_DOWNLOAD to enable this.
+
+ * src/pkgdeps.cpp (promote): Macro redefined in terms of...
+ (with_flags, with_download): ...these new macros; implement and...
+ (pkgXmlDocument::ResolveDependencies): ...use them to enable/schedule
+ ACTION_DOWNLOAD only when expected that it may be necessary.
+
+2011-11-06 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Fix packaging anomalies for source and licence distributions.
+
+ * Makefile.in (licdist): Link README from ${CURDIR}, not from '..'.
+ (srcdist): Explicitly link pkginfo.c from ${CURDIR} to src/pkginfo,

+ link srcdist-doc into src/pkginfo.
+
+2011-11-06 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Bump version number for subsequent CVS snapshots.
+

+ [DEBUG_TRACE_DEPENDENCIES]: Eliminate diagnostic noise.
+
+2011-10-11 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Fix --download-only vs. --reinstall conflict.
+
+ * src/pkgexec.cpp (pkgActionItem::Execute) [OPTION_DOWNLOAD_ONLY]:
+ Test for explicit inequality, rather than equality to zero; since the
+ 2011-08-30 update, which made --download-only also imply --reinstall,
+ it will test as non-zero when --reinstall is specified, even though
+ --download-only is not.
+
+2011-10-07 Keith Marshall <keithmarshall@users.sourceforge.net>
