NAME
       lwp-download - Fetch large files from the web

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

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'...
