Hello all,
I'm glad to announce the release of {prj_name} {prj_version}:
{prj_urlhome}
About
=====
psutil (process and system utilities) is a cross-platform library for \
retrieving information on running processes and system utilization (CPU, \
memory, disks, network) in Python. It is useful mainly for system \
monitoring, profiling and limiting process resources and management of \
running processes. It implements many functionalities offered by command \
line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, \
nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It \
currently supports Linux, Windows, macOS, Sun Solaris, FreeBSD, OpenBSD, \
NetBSD and AIX. Supported Python versions are cPython 3.6+ and PyPy.
