+    * src/detect.c (detect_parts): call bsdl_scan_file() if configure result indicates inclusion of BSDL subsystem
+    * src/cmd/cmd.c: include cmd_svf and cmd_bsdl based on configure result
+    * src/Makefile.am (jtag_DEPENDENCIES): link to libsvf.a and libbsdl.a based on configure result
+    * src/cmd/Makefile.am (libcmd_a_SOURCES): compile svf.c and bsdl.c based on configure result
+    * configure.ac: added --enable-svf and --enable-bsdl
     * README.svf: contents moved to doc/UrJTAG.txt, file deleted
     * data/Makefile.am (nobase_dist_pkgdata_DATA): fixed merge results
     * many files: integration of BSDL parser
