Use: "webdav",

Short: "A simple to use WebDAV server",
|
|
Long: `If you don't set "config", it will look for a configuration file called
|
|
config.{json, toml, yaml, yml} in the following directories:
|
|
|
|
- ./
|
|
- /etc/webdav/
|
|
|
|
The precedence of the configuration values are as follows:
|
|
|
|
- flags
|
|
- environment variables
|
|
- configuration file
|
|
- defaults
|
|
|
|
The environment variables are prefixed by "WD_" followed by the option
|
|
name in caps. So to set "cert" via an env variable, you should
|
|
set WD_CERT.`,
