   > @Xuanwo Hi, `oli` seems to be an awesome tool rocket I would like to get involved in the development!
   > 
   > Before I can start, I would like to introduce a config file to `oli`. IMHO a single config file is easier to manage than a handful of env vars.
   > 
   > The config file consists of multiple `profile`s, each `profile` represents a service users want to access. Users are able to specify the endpoint, credentials and other necessary parameters in each `profile`. The config file might look like this(the format doesn't matters, I just prefer toml now):
   > 
   > ```toml
   > # ~/.oli/config.toml
   > 
   > [[profiles]]
   > name = "mys3" # required
   > service = "s3" # required
   > endpoint = "" # optional
   > access-key = "<redacted>"
   > secret-key = "<redacted>"
   > 
   > [[profiles]]
   > name = "myaz" # required
   > service = "azblob" # required
   > endpoint = "" # optional
   > access-key = "<redacted>"
   > secret-key = "<redacted>"
   > ```
   > 
   > When users want to interact with multiple services, like copying objects across services, they need to run
   > 
   > ```
   > oli cp mys3://bucket/1.txt myaz://bucket2/1.txt
   > ```
   > 
   > Please note that the profile name is used as scheme to distinguish different services here.

   > I think the advantages of the config file over env vars including but not limited to:
   > 
   > 1. it is easier to manage a config file than exporting a lot of env vars in a shell rc file
   > 2. the config file can be strongly typed(like toml), it is easier to validate the config
   > 3. it is more straightforward to see which service has been configured with a config file

   I think we can hide the bucket from the path and move it into the config profile?
