### - Qucs -
Installed Files

The Qucs system needs several programs. These are installed during the installation process. The path of Qucs is determined during the installation (`configure` script). The following explanations assume the default path (`/usr/local/`).
`/usr/local/bin/qucs` - the GUI
`/usr/local/bin/qucsator` - the simulator (console application)
`/usr/local/bin/qucsedit` - a simple text editor
`/usr/local/bin/qucshelp` - a small program displaying the help system
`/usr/local/bin/qucstrans` - a program for calculation transmission line parameters
`/usr/local/bin/qucsfilter` - a program synthesizing filter circuits
`/usr/local/bin/qucsconv` - a file format converter (console application)
All programs are stand-alone applications and can be started independently. The main program (GUI)
calls `qucsator` when performing a simulation,
calls `qucsedit` when showing text files,
calls `qucshelp` when showing the help system,
calls `qucstrans` when calling this program from menu "Tools",
calls `qucsfilter` when calling this program from menu "Tools",
calls `qucsconv` when placing the SPICE component and when performing a simulation with the SPICE component.
Furthermore, the following directories are created during installation:
`/usr/local/share/qucs/bitmaps` - contains all bitmaps (icons etc.)
`/usr/local/share/qucs/docs` - contains HTML documents for the help system
`/usr/local/share/qucs/lang` - contains the translation files

#### Command line arguments
