tonight's changes, the progress bar and the new -w option

Version XX

Daniel (21 February 2000):

- I added the -w/--write-out flag and some variables to go with it. -w is a

  single string, whatever you enter there will be written out when curl has

  completed a successful request. There are some variable substitutions and

  they are specifed as '%{variable}' (without the quotes). Variables that

  exist as of this moment are:

        total_time     - total transfer time in seconds (with 2 decimals)

        size_download  - total downloaded amount of bytes

        size_upload    - total uploaded amount of bytes

        speed_download - the average speed of the entire download

        speed_upload   - the average speed of the entire upload

  I will of course add more variables, but I need input on these and others.

- It struck me that the -# progress bar will be hard to just apply on the new

  progress bar concept. I need some feedback on this before that'll get re-

  introduced! :-/

- Jörn Hartroth brought me some fixes for the progress meter and I continued

  working on it. It seems to work for http download, http post, ftp download
