DESCRIPTION
|
|
variables.go contains a list of structs that provide a variable Name, type in
|
|
a string format, a function for updating the variable in the Config struct
|
|
from a string, and finally, a validation function to check the validity of the
|
|
corresponding field value in the Config.
