+Subject: [PATCH 1/1] logs: optionally use base filenames to report src files
+
+Problem:  Logs are nice in that they report the source file,
+routine, and line number where an issue occurs.  But the
+file is printed as the absolute filename.  Users do not
+need to see a long spew of path directory names where the package
+was built.  It just confuses things.
+
+Solution:  Optionally chop off all leading directories so that just
+the source filename ie. basename is printed.  This is done by
+setting a #ifdef LXC_LOG_USE_BASENAME check in the code.  That
+define is done via the optional --enable-log-src-basename provided
+at configure time.
+
+Using __BASE_FILE__ instead of __FILE__ did not work.  It
+refers to the file name as presented to the compile
+machinery, and that may still be the absolute pathname to
+the file.
