+The build system now look for a system installed googletest or falls
+back to the bundled copy of googletest otherwise.
+
+* CMakeLists.txt: Add call to find_package(GTest).
+(include_directories): Remove "src/googletest/googletest/include" from
+arg.
+* src/CMakeLists.txt[NOT GTEST_FOUND]: Define the gtest and gtest_main
+libraries when GTEST_FOUND is false.  Globally include the googletest
+headers here.  Define aliases for the gtest and gtest_main libraries
+that match those defined by the FindGTest module.
+* src/tests/CMakeLists.txt: Replace references to gtest_main and gtest
+by GTest::Main and GTest::GTest, respectively.

+@item binload
+Load data into a binary file using simple commands from the input.
+@item binorder
+Sort, merge, search, retrieve or generate test data consisting of fixed size
+binary records.
+@item binreplace
+Find or find/replace in binary files.
+@item binsplit
+Split test data consisting of fixed size binary records into one or more
+output streams.
+@item chardiff
+Find changes between two files at the character level.  Unlike \"diff\", it
+lists just the characters that differ, so if the 40,000th character is
+different only that one character will be shown, not the entire line.
+@item columnadd
+Add columns of integers, decimals, and/or times.
+@item datasniffer
+A utility for formatting binary data dumps.
+@item dmath
+Double precision interactive command line math calculator.
+@item extract
+Extract and emit data from text files based on character or token position.
+@item execinput
+A utility that reads from STDIN and executes each line as a command in a
+sub-process.
+@item indexed_text
+A utility for rapid retrieval of text by line numbers, in any order, from a
+text file.
+@item mdump
+Format binary data.
+@item msgqueue
+Create message queues and send/receive messages.
+@item mbin
+@itemx mbout
+Multiple buffer in and out.  Used for buffering a lot of data between a slow
+device and a fast device.  Mostly for buffering streaming tape drives for use
+with slower network connections, so that streaming is maintained as much as
+possible to minimize wear on the tape device.
+@item pockmark
+Corrupt data streams - useful for testing error correction and data recovery.
