3 zip File Creation
The file/zip library provides
utilities to create zip archive files, which are compatible
with both Windows and Unix (including Mac OS X) unpacking. The actual
compression is implemented by deflate.
Creates zip-file, which holds the complete content of all
paths. The given paths are all expected to be
relative path names of existing directories and files (i.e., relative
to the current directory). If a nested path is provided as a
path, its ancestor directories are also added to the
resulting zip file, up to the current directory (using
pathlist-closure). Files are packaged as usual for
zip files, including permission bits for both Windows and Unix
(including Mac OS X). The permission bits are determined by
file-or-directory-permissions, which does not preserve the
distinction between owner/group/other permissions. Also, symbolic
links are always followed.
Zips each of the given paths, and packages it as a zip
“file” that is written directly to out. Unlike
zip, the specified paths are included as-is; if a
directory is specified, its content is not automatically added, and
nested directories are added without parent directories.
A parameter that controls output during a zip
operation. Setting this parameter to a true value causes zip
to display to (current-error-port) the filename that is
currently being compressed.
