The library supports the programmer to develop an application for the text console. It allows the simultaneous handling of multiple text windows on the screen.
 The C++ class design was inspired by the Qt framework. It provides common controls like dialog boxes, push buttons, check boxes, radio buttons, input lines, list boxes, status bars and so on.

+Frequently Asked Questions
+==========================
+
+
+What is FINAL CUT?
+------------------
+
+The Final Cut is a C++ class library and a widget toolkit with full mouse 
+support for creating a text-based user interface. It's based on the Termcap
+library and has its own cursor optimization and window management.
+
+
+Are Windows and DOS supported by FINAL CUT?
+-------------------------------------------
+
+You need an operating system environment that implements a POSIX system 
+call API. This can be realized in Windows with the Cygwin project.
+
+
+Is my platform supported?
+-------------------------
+
+The supported platforms are Linux, FreeBSD, NetBSD, OpenBSD, macOS, 
+Cygwin on Microsoft Windows and Oracle Solaris
+
+
+What do I need to write my own programs with FINAL CUT?
+-------------------------------------------------------
+
+You need a C++ compiler like GCC (g++) or Clang (clang++).
+
+
+What do I need to build this library?
+-------------------------------------
+
+You need three things:
+
+1. C++ compiler like GCC (g++) or Clang (clang++).
+
+2. The GNU building tools
+
+    *For example, in a Debian-based distribution it would be 
+    the following packages:*
+
+    * autotools-dev
+    * automake
+    * autoconf
+    * autoconf-archive
+    * libtool
+
+3. Development packages for following libraries:
+
+    * C standard library
+    * C++ standard library
+    * Termcap library *(mostly part of the curses library)*
+    * General Purpose Mouse library *(optional, only if you need 
+      mouse support on the Linux console)*
+
+    *For example, in a Debian-based distribution it would be the following 
+    packages:*
+
+    * libglib2.0-dev
+    * libstdc++-6-dev
+    * libtinfo-dev
+    * libncurses5-dev
+    * libgpm-dev
+
+
+How to compile FINAL CUT without gpm support?
+---------------------------------------------
+
+```bash
+  ./configure --without-gpm
+```
+
+
+What do I need to compile the unit tests?
+-----------------------------------------
+
+You need the unit testing framework CppUnit.
+
+
+How can I fix display problems?
+-------------------------------
+
+* Make sure that the environment variable TERM has the right 
+  terminal name.
+
+* With the command "`msgcat --color=test`" you can test whether 
+  the colors are displayed correctly in the terminal
+
+* If characters are not displayed in the right place on the screen, 
+  it may help to disable cursor optimization for your program with 
+  the parameter *--no-optimized-cursor*.
+
+* If terminal detection did not work, it is useful to turn off the terminal 
+  detection with the parameter *--no-terminal-detection*.
+
+* If the color palette redefinition causes problems, you can switch off 
+  the color mapping with the parameter *--no-color-change*.
