annotate scripts/miscellaneous/zip.m @ 19257:a4e993343e93

Overhaul the archive family (bzip2, gzip, zip, tar) of m-files. * NEWS: Announce changes to archive family of functions. * bunzip2.m: Redo docstring. Use common variable names between docstring and function. Remove file from test statistics. Default to placing uncompressed files in same directory as the compressed one. * bzip2.m: Redo docstring. Use common variable names between docstring and function. Add extensive BIST test. * gunzip.m: Redo docstring. Use common variable names between docstring and function. Remove file from test statistics. Default to placing uncompressed files in same directory as the compressed one. * gzip.m: Redo docstring. Remove input validation test that is no longer applicable. * __xzip__.m: Create output directory if it is named, but does not yet exist. Check return code of mkdir and issue an error if it is unsuccesful. Use the caller's name (gzip or bzip2) in error messages. Rename subfunction myfileparts to fname_only for slightly more clarity. Add FIXME note that compression of directories does not work. * tar.m: Redo docstring. Use common variable names between docstring and function. Add extensive BIST test. * untar.m: Redo docstring. Use common variable names between docstring and function. Remove file from test statistics. Default to placing uncompressed files in same directory as the compressed one. * unzip.m: Redo docstring. Use common variable names between docstring and function. Remove file from test statistics. Default to placing uncompressed files in same directory as the zip archive. * zip.m: Redo docstring. Use common variable names between docstring and function. Add extensive BIST test.
