|
||||
Subject: [PATCH] Introduce CHICKEN_REPOSITORY_EXTRA
|
||||
|
||||
This environment variable works like CHICKEN_REPOSITORY but supports
|
||||
multiple paths separated by `:'. Those paths are searched after
|
||||
CHICKEN_REPOSITORY when loading extensions via `require-library' and
|
||||
friends. It can be accessed and changed at runtime via the new procedure
|
||||
`repository-extra-paths' which is analog to `repository-path'.
