+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+New in 2.7:
+
+* gperf is now a stand-alone package, untied from libg++.
+* Autoconfiguring.
+* Removed the "-a" and "-g" options, extended the "-L" option instead.
+* Removed the "-p" option, it is the default.
+* Added long options ("--help", "--version" etc.).
+* 8-bit cleanliness is now the default; use "-7" to get the old behaviour.
+* Compiles with any C++ compiler.
+* Numerous small improvements.

+.SH NAME
+gperf \- generate a perfect hash function from a key set
+.SH SYNOPSIS
+.B gperf 
+[ 
+.B \-adghijklnoprsStv
+] [ 
+.I keyfile
+]
+.SH DESCRIPTION
+
+\fIgperf\fP reads a set of ``keys'' from \fIkeyfile\fP (or, by
+default, from the standard input) and attempts to find a non-minimal
+perfect hashing function that recognizes a member of the key set in
+constant, i.e., O(1), time.  If such a function is found the program
+generates a pair of \fIC\fP source code routines that perform the
+hashing and table lookup.  All generated code is directed to the
+standard output.
+
+Please refer to the \fIgperf.texi\fP file for more information.
+This file is distributed with \fIgperf\fP release.

+GNU `gperf' generates perfect hash functions.
+
+Usage: ../src/gperf [OPTION]... [INPUT-FILE]
+
+If a long option shows an argument as mandatory, then it is mandatory
+for the equivalent short option also.
+
+Input file interpretation:
+  -e, --delimiters=DELIMITER-LIST
+                         Allow user to provide a string containing delimiters
+                         used to separate keywords from their attributes.
+                         Default is ",\n".
+  -t, --struct-type      Allows the user to include a structured type
+                         declaration for generated code. Any text before %%
+                         is considered part of the type declaration. Key
+                         words and additional fields may follow this, one
+                         group of fields per line.
+
+Language for the output code:
+  -L, --language=LANGUAGE-NAME
+                         Generates code in the specified language. Languages
+                         handled are currently C++, ANSI-C, C, and KR-C. The
+                         default is C.
+
+Details in the output code:
+  -K, --slot-name=NAME   Select name of the keyword component in the keyword
+                         structure.
+  -H, --hash-fn-name=NAME
+                         Specify name of generated hash function. Default is
+                         `hash'.
+  -N, --lookup-fn-name=NAME
+                         Specify name of generated lookup function. Default
+                         name is `in_word_set'.
+  -Z, --class-name=NAME  Specify name of generated C++ class. Default name is
+                         `Perfect_Hash'.
+  -7, --seven-bit        Assume 7-bit characters.
+  -c, --compare-strncmp  Generate comparison code using strncmp rather than
+                         strcmp.
+  -C, --readonly-tables  Make the contents of generated lookup tables
+                         constant, i.e., readonly.
+  -E, --enum             Define constant values using an enum local to the
+                         lookup function rather than with defines.
+  -I, --includes         Include the necessary system include file <string.h>
+                         at the beginning of the code.
+  -G, --global           Generate the static table of keywords as a static
+                         global variable, rather than hiding it inside of the
+                         lookup function (which is the default behavior).
+  -W, --word-array-name=NAME
+                         Specify name of word list array. Default name is
+                         `wordlist'.
+  -S, --switch=COUNT     Causes the generated C code to use a switch
+                         statement scheme, rather than an array lookup table.
+                         This can lead to a reduction in both time and space
+                         requirements for some keyfiles. The COUNT argument
+                         determines how many switch statements are generated.
+                         A value of 1 generates 1 switch containing all the
+                         elements, a value of 2 generates 2 tables with 1/2
+                         the elements in each table, etc. If COUNT is very
+                         large, say 1000000, the generated C code does a
+                         binary search.
+  -T, --omit-struct-type
+                         Prevents the transfer of the type declaration to the
+                         output file. Use this option if the type is already
+                         defined elsewhere.
+
+Algorithm employed by gperf:
+  -k, --key-positions=KEYS
+                         Select the key positions used in the hash function.
+                         The allowable choices range between 1-126, inclusive.
+                         The positions are separated by commas, ranges may be
+                         used, and key positions may occur in any order.
+                         Also, the meta-character '*' causes the generated
+                         hash function to consider ALL key positions, and $
+                         indicates the ``final character'' of a key, e.g.,
+                         $,1,2,4,6-10.
+  -l, --compare-strlen   Compare key lengths before trying a string
+                         comparison. This helps cut down on the number of
+                         string comparisons made during the lookup.
+  -D, --duplicates       Handle keywords that hash to duplicate values. This
+                         is useful for certain highly redundant keyword sets.
+  -f, --fast=ITERATIONS  Generate the gen-perf.hash function ``fast''. This
+                         decreases gperf's running time at the cost of
+                         minimizing generated table size. The numeric
+                         argument represents the number of times to iterate
+                         when resolving a collision. `0' means ``iterate by
+                         the number of keywords''.
+  -i, --initial-asso=N   Provide an initial value for the associate values
+                         array. Default is 0. Setting this value larger helps
+                         inflate the size of the final table.
+  -j, --jump=JUMP-VALUE  Affects the ``jump value'', i.e., how far to advance
+                         the associated character value upon collisions. Must
+                         be an odd number, default is 5.
+  -n, --no-strlen        Do not include the length of the keyword when
+                         computing the hash function.
+  -o, --occurrence-sort  Reorders input keys by frequency of occurrence of
+                         the key sets. This should decrease the search time
+                         dramatically.
+  -r, --random           Utilizes randomness to initialize the associated
+                         values table.
+  -s, --size-multiple=N  Affects the size of the generated hash table. The
+                         numeric argument N indicates ``how many times larger
+                         or smaller'' the associated value range should be,
+                         in relationship to the number of keys, e.g. a value
+                         of 3 means ``allow the maximum associated value to
+                         be about 3 times larger than the number of input
+                         keys.'' Conversely, a value of -3 means ``make the
+                         maximum associated value about 3 times smaller than
+                         the number of input keys. A larger table should
+                         decrease the time required for an unsuccessful
+                         search, at the expense of extra table space. Default
+                         value is 1.
+
+Informative output:
+  -h, --help             Print this message.
+  -v, --version          Print the gperf version number.
+  -d, --debug            Enables the debugging option (produces verbose
+                         output to the standard error).
+
