+ * This is a compact "tar" program whose primary goal is small size.
+ * Statically linked, it can be very small indeed. This serves a number
+ * of goals:
+ * o a testbed for libarchive (to check for link pollution),
+ * o a useful tool for space-constrained systems (boot floppies, etc),
+ * o a place to experiment with new implementation ideas for bsdtar,
+ * o a small program to demonstrate libarchive usage.
+ *
+ * Use the following macros to suppress features:
+ * NO_BZIP2 - Implies NO_BZIP2_CREATE and NO_BZIP2_EXTRACT
+ * NO_BZIP2_CREATE - Suppress bzip2 compression support.
+ * NO_BZIP2_EXTRACT - Suppress bzip2 auto-detection and decompression.
+ * NO_COMPRESS - Implies NO_COMPRESS_CREATE and NO_COMPRESS_EXTRACT
+ * NO_COMPRESS_CREATE - Suppress compress(1) compression support
+ * NO_COMPRESS_EXTRACT - Suppress compress(1) auto-detect and decompression.
+ * NO_CREATE - Suppress all archive creation support.
+ * NO_CPIO_EXTRACT - Suppress auto-detect and dearchiving of cpio archives.
+ * NO_GZIP - Implies NO_GZIP_CREATE and NO_GZIP_EXTRACT
+ * NO_GZIP_CREATE - Suppress gzip compression support.
+ * NO_GZIP_EXTRACT - Suppress gzip auto-detection and decompression.
+ * NO_LOOKUP - Try to avoid getpw/getgr routines, which can be very large
+ * NO_TAR_EXTRACT - Suppress tar extraction
+ *
+ * With all of the above macros defined (except NO_TAR_EXTRACT), you
+ * get a very small program that can recognize and extract essentially
+ * any uncompressed tar archive. On FreeBSD 5.1, this minimal program
+ * is under 64k, statically linked, which compares rather favorably to
+ * main(){printf("hello, world");}
+ * which is over 60k statically linked on the same operating system.
+ * Without any of the above macros, you get a static executable of
+ * about 180k with a lot of very sophisticated modern features.
+ * Obviously, it's trivial to add support for ISO, Zip, mtree,
+ * lzma/xz, etc. Just fill in the appropriate setup calls.
