-/*
- * Main program to compile sshzlib.c into a zlib decoding tool.
- *
- * This is potentially a handy tool in its own right for picking apart
- * Zip files or PDFs or PNGs, because it accepts the bare Deflate
- * format and the zlib wrapper format, unlike 'zcat' which accepts
- * only the gzip wrapper format.
- *
- * It's also useful as a means for a fuzzer to get reasonably direct
- * access to PuTTY's zlib decompressor.
