NAME
       lwp-download - Fetch large files from the web

SYNOPSIS
        lwp-download [-a] [-s] <url> [<local path>]

        Options:

          -a   save the file in ASCII mode
          -s   use HTTP headers to guess output filename

DESCRIPTION
       The lwp-download program will save the file at url to a local file.

       If local path is not specified, then the current directory is assumed.

       If local path is a directory, then the last segment of the path of the url is appended to
       form a local filename.  If the url path ends with slash the name "index" is used.  With the
       -s option pick up the last segment of the filename from server provided sources like the
       Content-Disposition header or any redirect URLs.  A file extension to match the server
       reported Content-Type might also be appended.  If a file with the produced filename already
       exists, then lwp-download will prompt before it overwrites and will fail if its standard
       input is not a terminal.  This form of invocation will also fail is no acceptable filename
       can be derived from the sources mentioned above.

       If local path is not a directory, then it is simply used as the path to save into.  If the
       file already exists it's overwritten.

       The lwp-download program is implemented using the libwww-perl library.  It is better suited
       to down load big files than the lwp-request program because it does not store the file in
       memory.  Another benefit is that it will keep you updated about its progress and that you
       don't have much options to worry about.

       Use the "-a" option to save the file in text (ASCII) mode.  Might make a difference on DOSish
       systems.

EXAMPLE
       Fetch the newest and greatest perl version:

        $ lwp-download http://www.perl.com/CPAN/src/latest.tar.gz
        Saving to 'latest.tar.gz'...
