+# Examples
+
+These examples can be run by running `cargo run --example example_name`
+
+## dump.rs
+
+Prints out details about the current process (the dumper itself), or a process specifed by PID
+
+## interface_stats.rs
+
+Runs continually and prints out how many bytes/packets are sent/received.  Press ctrl-c to exit the example:
+
+```text
+       Interface: bytes recv                         bytes sent

+
+## netstat.rs
+
+Prints out all open and listening TCP/UDP sockets, along with the owning process.  The
+output format is very similar to the standard `netstat` linux utility:
+
+```text
+Local address              Remote address             State           Inode    PID/Program name
+0.0.0.0:53                 0.0.0.0:0                  Listen          30883        1409/pdns_server
+0.0.0.0:51413              0.0.0.0:0                  Listen          24263        927/transmission-da
+0.0.0.0:35445              0.0.0.0:0                  Listen          21777        942/rpc.mountd
+0.0.0.0:22                 0.0.0.0:0                  Listen          27973        1149/sshd
+0.0.0.0:25                 0.0.0.0:0                  Listen          28295        1612/master
+```
+
+## pressure.rs
+
+Prints out CPU/IO/Memory pressure information
+
+## ps.rs
+
+Prints out all processes that share the same tty as the current terminal.  This is very similar to the standard
+`ps` utility on linux when run with no arguments:
+
+```text
+  PID TTY          TIME CMD
+ 8369 pty/13       4.05 bash
+23124 pty/13       0.23 basic-http-serv
+24206 pty/13       0.11 ps
+```
+
+## self_memory.rs
+
+Shows several ways to get the current memory usage of the current process
+
+```text
+PID: 21867
+Memory page size: 4096
+== Data from /proc/self/stat:
+Total virtual memory used: 3436544 bytes
+Total resident set: 220 pages (901120 bytes)
+
+== Data from /proc/self/statm:
+Total virtual memory used: 839 pages (3436544 bytes)
+Total resident set: 220 pages (901120 byte)s
+Total shared memory: 191 pages (782336 bytes)
+
+== Data from /proc/self/status:
+Total virtual memory used: 3436544 bytes
+Total resident set: 901120 bytes
+Total shared memory: 782336 bytes
+```
+
+## lsmod.rs
+
+This lists all the loaded kernel modules, in a simple tree format.
+
+## diskstat.rs
+
+Lists IO information for local disks:
+
+```text
+sda1 mounted on /:
+  total reads: 7325390 (13640070 ms)
+  total writes: 124191552 (119109541 ms)
+  total flushes: 0 (0 ms)
+```
+
+Note: only local disks will be shown (not NFS mounts,
+and disks used for ZFS will not be shown either).
+
+## lslocks.rs
+
+Shows current file locks in a format that is similiar to the `lslocks` utility.
+
+## mountinfo.rs
+
+Lists all mountpoints, along with their type and options:
+
+```text
+sysfs on /sys type sysfs (noexec,relatime,nodev,rw,nosuid)
+proc on /proc type proc (noexec,rw,nodev,relatime,nosuid)
+udev on /dev type devtmpfs (rw,nosuid,relatime)
+  mode = 755
+  nr_inodes = 4109298
+  size = 16437192k
+devpts on /dev/pts type devpts (nosuid,rw,noexec,relatime)
+  gid = 5
+  ptmxmode = 000
+  mode = 620
+tmpfs on /run type tmpfs (rw,nosuid,noexec,relatime)
+  size = 3291852k
+  mode = 755
+/dev/sda1 on / type ext4 (rw,relatime)
+  errors = remount-ro
+```
+
+## process_hierarchy.rs
+
+Lists all processes as a tree. Sub-processes will be hierarchically ordered beneath their parents.
+
+```text
+1       /usr/lib/systemd/systemd --system --deserialize 54
+366         /usr/lib/systemd/systemd-journald
+375         /usr/lib/systemd/systemd-udevd
