db_info: Get the connection info for a specific database
In vaulot/dvutils: A set of utilities

Description Usage Arguments Value Examples

To be used with db_connect (see the example). For the database on Scrol server, one can go though SSH (e.g. when using EduRoam or at NTU). However at present this connection does not work. It is first necessary to set up a tunnel through Putty (see https://blog.devolutions.net/2017/4/how-to-configure-an-ssh-tunnel-on-putty). Same thing for SSL (Google database). The connection info are now stored in a file (my.cnf). See https://github.com/r-dbi/RMySQL/issues/131

db_info(
  database_name,
  file_cnf = "C:/daniel.vaulot@gmail.com/Databases/MySQL/my.cnf"
)

`database_name`	One of the following choices "rcc", "pr2_google", "metapr2_google", "rcc_local", "pr2_local", "metapr2_local"
`file_cnf`	by default "C:/daniel.vaulot@gmail.com/Databases/MySQL/my.cnf" but can be moved to another location (e.g. when using dvutils on a server)
