+[`pacman`](https://wiki.archlinux.org/index.php/pacman) defines subcommands via flags.
+
+Here, `-S` is a short flag subcommand:
+```console
+$ pacman -S package
+Installing package...
+
+```
+
+Here `--sync` is a long flag subcommand:
+```console
+$ pacman --sync package
+Installing package...
+
+```
+
+Now the short flag subcommand (`-S`) with a long flag:
+```console
+$ pacman -S --search name
+Searching for name...
+
+```
+
+And the various forms of short flags that work:
+```console
+$ pacman -S -s name
+Searching for name...
+
+$ pacman -Ss name
+Searching for name...
+
+```
+*(users can "stack" short subcommands with short flags or with other short flag subcommands)*
+
+In the help, this looks like:
+```console
+$ pacman -h
+pacman 5.2.1
+Pacman Development Team
+package manager utility
+
+USAGE:
+ pacman[EXE] <SUBCOMMAND>
+
+OPTIONS:
+ -h, --help Print help information
+ -V, --version Print version information
+
+SUBCOMMANDS:
+ help Print this message or the help of the given subcommand(s)
+ query -Q --query Query the package database.
+ sync -S --sync Synchronize packages.
+
+$ pacman -S -h
+pacman[EXE]-sync
+Synchronize packages.
+
+USAGE:
+ pacman[EXE] {sync|--sync|-S} [OPTIONS] [--] [package]...
+
+ARGS:
+ <package>... packages
+
+OPTIONS:
+ -h, --help Print help information
+ -i, --info view package information
+ -s, --search <search>... search remote repositories for matching strings
+
+```
+
+And errors:
+```console
+$ pacman -S -s foo -i bar
+? failed
+error: The argument '--search <search>...' cannot be used with '--info'
+
+USAGE:
+ pacman[EXE] {sync|--sync|-S} --search <search>... <package>...
+
+For more information try --help
+
+```
+
+**NOTE:** Keep in mind that subcommands, flags, and long flags are *case sensitive*: `-Q` and `-q` are different flags/subcommands. For example, you can have both `-Q` subcommand and `-q` flag, and they will be properly disambiguated.
+Let's make a quick program to illustrate.
