This simply parses the command line arguments using the default golang
|
||
|
|
package called 'flag'. This can be used as a simple template to parse
|
||
|
|
command line arguments in other programs.
|
||
|
|
|
||
|
|
It puts everything in the 'config' package which I think is a good
|
||
|
|
wrapper around the 'flags' package and doesn't need a whole mess of
|
||
|
|
global variables
