ECHO Spider.bat,  Version 0.22 alpha for Windows NT 4 and later

ECHO Display the validity of hyperlinks in a group of locally stored HTML files.

```
ECHO.
```
```
ECHO Usage:  SPIDER  [ /E [ error# ] ]
```
```
ECHO.
```

ECHO Where:  /E      forces display of errors only (default is ALL results)

ECHO         error#  will display errors of this type only (e.g. /E 404)

```
ECHO.
```

ECHO Notes:  Must be started in the directory where the HTML files are located.

ECHO         Uses WGET --spider to check the validity of the hyperlinks; tested

ECHO         with WGET that came with ApacheFriends XAMPP for windows Version 1.0

ECHO         available at http://www.apachefriends.org/

ECHO         Also uses CUT, a compiled version of my CUT.PL script, which is

ECHO         available at http://www.robvanderwoude.com/cut.html

ECHO         Being an alpha version, and a quick-and-dirty one at that, I can in

ECHO         no way guarantee this batch file will work correctly on any computer;

ECHO         in fact I can guarantee there are still some bugs that need correction.
