Changes in version 1.4: This version produces version 1 files with support for safe recovery of undamaged members from multimember files. The new option "--member-size", that produces multimember files, has been added. The new option "--volume-size", that splits the compressed output into several volume files, has been added. The new option "--output", that sends output to a file when reading from standard input, has been added. This version is able to read from some types of non regular files if "--stdout" is specified. Lziprecover, a member recoverer program for lzip compressed files, has been added to the distribution. "testsuite/unzcrash.cc" now tests all 1-byte errors instead of only 1-bit errors.
