// this is the "wrapper" header file for the zip/unzip functions to expose to BOINC clients
// CMC - 18/03/2004, Oxford University for BOINC project
// released under the BOINC license

// note that I've disabled zip encryption to try and simplify things
// (zip encryption is fairly weak and easy to break anyway)

// you will need to link against the library (boinc_zip.lib on Windows-Release,
// boinc_zipd.lib for Windows-Debug, or libboinc_zip.a on Unix & Mac OSX)

// also you will need to include filesys.C in your project
// (decided not to add that in the lib due to version problems that may arise)

// send in an input file or path wildcard, output filename, and basic options

// default options for zip (bZip = true) are "-j9q" which is 
// DON'T recurse/list subdirectories, best compression, quiet operation
// call it with bZiptype = ZIP_IP to zip, bZip = UNZIP_IT to unzip (duh)

// note boinc_zip is overloaded for ease of use
// i.e. you can just send char filenames, or std::strings, or preferably
// a vector of std::string of filenames to add to the zip archive

// there is also a crude but handy wildcard matching function to build
// the vector of string's, and probably better than using wildcards in zip
// across platforms
