103
|
|
|
|
|
|
|
|
104
|
|
|
|
|
|
|
This is a drop-in replacement for C based on |
105
|
|
|
|
|
|
|
C. Usage is the same, except in the case |
106
|
|
|
|
|
|
|
when documentation for a module cannot be found on the |
107
|
|
|
|
|
|
|
local machine, in which case a query (via LWP or SOAP::Lite) will |
108
|
|
|
|
|
|
|
be made to a remote pod repository and, if the documentation is |
109
|
|
|
|
|
|
|
found there, the results will be displayed as usual. |

The values of C<$pod_server>, C<$soap_uri> and |
