    Using Tcl I want to be able to read from and write to zip files which may
    contain encrypted data (zip 2.0 compatible only).

    I've looked at vsf::zip which looks very good, but seems to be read-only and
    doesn't pass much info on the files contained inside the zip file back so it
    can be used within Tcl code. Also, vsf::zip doesn't appear to cater for
    where files in the zip file are encrypted.

    Is there any work going on to make vsf::zip handle writing to zip files and
    handle encryption? Are there other packages which I should be looking at to
    get the features I want?

    I'm trying to get my head around how the vsf::zip code works and what would
    need to be changed to include encryption, etc..

    My lack of experience with C is not helping the process of doing this, but I
    can read it <slowly>.

    Any advice on ways to make the package include some or all of my
    requirements would be appreciated. I'm an experienced programmer, but am
    still fairly new to Tcl .

    My other thought was to somehow use the DLLs from the Info-Zip project to
    provide the required functionality. In the past I've used these DLLs from
    Visual Basic code, so it's not totally new territory to me. Am I correct my
    understanding that a module written in C is needed to handle communication
    between Tcl code and the DLLs? If so, is any documentation available to
    help me begin writing such a module?

    At present I'm working on Win 98 & XP, but also have access to Linux and
    would like my project to work there as well with as little change as
    possible.

    TIA

            Rob.
