status

the tools and library can read and write common zip files.  encryption
is not supported, as are zip64 and most other mostly irrelevant
extensions.

intro

zipfs consists of three parts:

• a read-only zip file system, allowing you to mount a zip file
  using styx.
  

• tools to read/list/write zip files.
• tool to rewrite zip file with files in different order.
• a library to read & write zip files.

see the manual pages getzip(1), zipstream(1) and zipfs(4) for more
information.  the library is currently undocumented.

install

make sure $ROOT is set.  now "mk install" to compile and install
the files.

when building from within inferno, insert SYSHOST=Inferno and ROOT=
in the mk invocations to override the values in the mkconfig.

todo

• determine inflate problem on input, where inflate wants one more
  byte than in input stream, and then returns it as leftover byte.
  

• compressed central directory (part of zip64?)

perhaps:

• zip64 extensions

• use attributes:
  0xd=unix -> uid,gid,times,links/device
  0x8 => undocumented charset encoding...
  0x7075 => info-zip utf-8 path
  0x6375 => info-zip utf-8 comment
