%description
 This is a prometheus exporter to get metrics of a samba server.
 It uses smbstatus to collect the data and converts the result into
 prometheus style data.
 The prometheus style data can be requested manually on port 9922
 using a http client. Or a prometheus database sever can be configured
 to collect the data by scraping port 9922 on the samba server.
