child 2471 194be299b700
permissions -rw-r--r--
Added more missing svn:keywords properties to some files (this should be the last of them before I never have to do this again)
Moved sm_memtable files in sqlite extension to sdk directory (to be consistent with topmenus)
Some extension source files had an incorrect extension name in their headers
