It can adapt dynamically to the displayed information depending on the terminal size. It can also work in client/server mode. Remote monitoring can be performed via a terminal or web interface. .sp \fBglances\fP is written in Python and uses the \fIpsutil\fP library to get information from your system. .SH OPTIONS .SH
