| 66 |  |  |  |  |  |  |  | 
| 67 |  |  |  |  |  |  | This module implements a www-like shell above WWW::Mechanize | 
| 68 |  |  |  |  |  |  | and also has the capability to output crude Perl code that recreates | 
| 69 |  |  |  |  |  |  | the recorded session. Its main use is as an interactive starting point | 
| 70 |  |  |  |  |  |  | for automating a session through WWW::Mechanize. | 
| 71 |  |  |  |  |  |  |  | 
| 72 |  |  |  |  |  |  | The cookie support is there, but no cookies are read from your existing | 
| 73 |  |  |  |  |  |  | browser sessions. See L on how to implement reading/writing | 
| 74 |  |  |  |  |  |  | your current browsers cookies. | 
| 75 |  |  |  |  |  |  |  | 
| 76 |  |  |  |  |  |  | =head2 Cnew %ARGS> | 
| 77 |  |  |  |  |  |  |  | 
| 78 |  |  |  |  |  |  | This is the constructor for a new shell instance. Some of the options | 
| 79 |  |  |  |  |  |  | can be passed to the constructor as parameters. | 
| 80 |  |  |  |  |  |  |  | 
| 81 |  |  |  |  |  |  | By default, a file C<.mechanizerc> (respectively C under Windows) | 
| 82 |  |  |  |  |  |  | in the users home directory is executed before the interactive shell loop is | 
| 83 |  |  |  |  |  |  | entered. This can be used to set some defaults. If you want to supply a different | 
| 84 |  |  |  |  |  |  | filename for the rcfile, the C parameter can be passed to the constructor : | 
| 85 |  |  |  |  |  |  |  | 
| 86 |  |  |  |  |  |  | rcfile => '.myapprc', | 
| 87 |  |  |  |  |  |  |  |
