This script should be called *manually* when we want to upgrade SSLError
|
|
|
|
|
`library` and `reason` mnemnonics to a more recent OpenSSL version.
|
|
|
|
|
|
|
|
|
|
It takes two arguments:
|
|
|
|
|
- the path to the OpenSSL include files' directory
|
|
|
|
|
(e.g. openssl-1.0.1-beta3/include/openssl/)
|
|
|
|
|
- the path to the C file to be generated
|
|
|
|
|
(probably Modules/_ssl_data.h)
