NAME
writelog - add a entry to an INN log file. SYNOPSIS
writelog name text... DESCRIPTION
The writelog script is used to write a log entry or send it as mail. The name parameter specifies the name of the log file where the entry should be written. If it is the word ``mail'' then the entry is mailed to the news administrator, <USER specified with --with-news-mas- ter at configure>. The data that is written or sent consists of the text given on the command line, followed by standard input indented by four spaces. Shlock(1) is used to avoid simultaneous updates to a single log file. HISTORY
