+\n\
+Basic Installation\n\
+==================\n\
+\n\
+   Briefly, the shell command `./configure && make && make install` should\n\
+configure, build, and install this package. The following more-detailed\n\
+instruction are generic; see the `README` file for instructions specific to\n\
+this package.\n\
+\n\
+   The `configure` shell script attempts to guess correct values for\n\
+various system-dependent variables used during compilation. It uses\n\
+those values within a `Makefile` to build for that POSIX system as\n\
+defined by `config.mak` which was generated by `configure`.\n\
+\n\
+Compilers and Options\n\
+=====================\n\
+\n\
+  Some systems require unusal options for compilation or linking that\n\
+the `configure` script does not know about. If you run into an issue\n\
+run `./configure --help` to figure out what you can do to fix the\n\
+behavoir.\n\
+\n\
+Installation Names\n\
+==================\n\
+\n\
+  By default, `make install` installs the package's command under\n\
+`/usr/local/bin`. You can specify an installation prefix other than `/usr/local/`\n\
+by giving `configure` the option `--prefix=PREFIX` to `configure`, the package uses\n\
+PREFIX as the prefix for installation programs and libraries.\n\
+Documentation and other data files still use the regular prefix.\n\
+\n\
+`configure` Invokation\n\
+======================\n\
+\n\
+  `configure` recongizes the following options to control its operations.\n\
+\n\
+  `--help`\n\
+     Prints a summary of all the options to `configure`, and exits.\n\
+  `--prefix=PREFIX`\n\
+     Sets the installation prefix.\n\
+  `CFLAGS`\n\
+    Sets the flags used during compilation.\n\
+\n\
+`configure` also accepts some other options. Run `configure --help` for more\n\
