+Qt is a cross-platform C++ application framework.  Qt's
+primary feature is its rich set of widgets that provide
+standard GUI functionality.
 
-Optional dependencies: unixodbc, freetds, OpenAL, libwebp, opus, snappy,
-wayland, and postgresql
+The following are optional dependencies that Qt will link
+against if they are detected at build time:
 
-Optional dependencies: openvg and firebird (not available
-at slackbuilds.org)

+============================================================
+
+OPTIONS
+
+To build the documentation pass DOCS=yes to the SlackBuild:
 
   DOCS=yes ./qt5.SlackBuild
 
-Note2: To build examples pass EXAMPLES=yes to the slackbuild
+To build the examples pass EXAMPLES=yes to the SlackBuild:
 
   EXAMPLES=yes ./qt5.SlackBuild
 
-Note3: To build support for proprietary media codecs (note that this
-will produce a non-redistributable package in some countries) pass
-PROPRIETARY_CODECS=yes to the slackbuild
+NOTE
+
+Building the documentation and examples creates a
+significantly larger package.

+
+ROUGH SIZE GUIDE
+
+Package size:
+
+  Qt alone:                              102M
+  With documentation:                    339M
+  With examples:                         391M
+  With both documentation and examples:  628M
+
+Minumum working space needed (size of source and package
+directories at end of build):
+
+  Qt alone:                              5018M
+  With documentation:                    6197M
+  With examples:                         6388M
+  With both documentation and examples:  7604M
+
+
+To build support for proprietary media codecs pass
+PROPRIETARY_CODECS=yes to the SlackBuild (this will produce
+a non-redistributable package in some countries):
 
   PROPRIETARY_CODECS=yes ./qt5.SlackBuild
 
-Note4: To disable support for pulseaudio pass PULSEAUDIO=no to the slackbuild
+To disable support for pulseaudio pass PULSEAUDIO=no to the
+SlackBuild:
 
   PULSEAUDIO=no ./qt5.SlackBuild
 
-(Qt will be automatically detect and disable pulseaudio if not installed.)
-
-Qt will also detect and use pcre2 if it is installed.
+Qt will automatically detect if it is not installed at build
+time and not provide support for it.
 
 
-NOTICE
+============================================================
 
-There is a qt5-legacy SlackBuild available for applications that
-might not run correctly with this version.
+NOTE
 
-Known Applications With Problems:
+After upgrading Qt5 it is important to rebuild qt5ct too, if
+it is installed, or some applications may not display or
+function correctly.
 
-speedcrunch: the widget drawer does not close properly.
+There is a qt5-legacy (5.7.1) SlackBuild that is available
+for older applications that do not run correctly with this
+version. However it will not coexist with this version.
+
+Please report any problems about applications that don't
+work correctly to the Qt5 maintainer or to the mailing list.
