+NAME
+       gperf - generate a perfect hash function from a key set
+
+SYNOPSIS
+       gperf [OPTION]... [INPUT-FILE]
+
+DESCRIPTION
+       GNU 'gperf' generates perfect hash functions.
+
+       If a long option shows an argument as mandatory, then it
+       is mandatory for the equivalent short option also.
+
+   Output file location:
+       --output-file=FILE Write output to specified file.
+
+       The results are written to standard output if no  output
+       file is specified or if it is -.
+
+   Input file interpretation:
+       -e, --delimiters=DELIMITER-LIST
+              Allow  user to provide a string containing delim-
+              iters  used  to  separate  keywords  from   their
+              attributes.  Default is ",".
+
+       -t, --struct-type
+              Allows the user to include a structured type dec-
+              laration 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.
+
+       --ignore-case
+              Consider upper and lower case ASCII characters as
+              equivalent. Note that locale dependent case  map-
+              pings are ignored.
+
+   Language for the output code:
+       -L, --language=LANGUAGE-NAME
+              Generates  code  in  the specified language. Lan-
+              guages 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 key-
+              word structure.
+
+       -F, --initializer-suffix=INITIALIZERS
+              Initializers for  additional  components  in  the
+              keyword structure.
+
+       -H, --hash-function-name=NAME
+              Specify  name of generated hash function. Default
+              is 'hash'.
+
+       -N, --lookup-function-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.
+
+       -l, --compare-lengths
+              Compare key lengths before trying a  string  com-
+              parison.  This  is necessary if the keywords con-
+              tain NUL bytes. It also helps  cut  down  on  the
+              number  of  string  comparisons  made  during the
+              lookup.
+
+       -c, --compare-strncmp
+              Generate comparison  code  using  strncmp  rather
+              than strcmp.
+
+       -C, --readonly-tables
+              Make the contents of generated lookup tables con-
+              stant, 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-table
+              Generate the static table of keywords as a static
+              global  variable, rather than hiding it inside of
+              the lookup function (which is the default  behav-
+              ior).
+
+       -P, --pic
+              Optimize  the  generated  table  for inclusion in
+              shared libraries.  This reduces the startup  time
+              of programs using a shared library containing the
+              generated code.
+
+       -Q, --string-pool-name=NAME
+              Specify name of string pool generated  by  option
+              --pic.  Default name is 'stringpool'.
+
+       --null-strings
+              Use  NULL  strings  instead  of empty strings for
+              empty keyword table entries.
+
+       -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 ta-
+              ble.   This  can lead to a reduction in both time
+              and space requirements  for  some  keyfiles.  The
+              COUNT  argument determines how many switch state-
+              ments 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  func-
+              tion.  The allowable choices range between 1-255,
+              inclusive.  The positions are separated  by  com-
+              mas,  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.
+
+       -D, --duplicates
+              Handle  keywords  that  hash to duplicate values.
+              This is useful for certain highly redundant  key-
+              word sets.
+
+       -m, --multiple-iterations=ITERATIONS
+              Perform multiple choices of the -i and -j values,
+              and choose the best results. This  increases  the
+              running time by a factor of ITERATIONS but does a
+              good job minimizing the generated table size.
+
+       -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 col-
+              lisions. Must be an odd number, default is 5.
+
+       -n, --no-strlen
+              Do not include the length  of  the  keyword  when
+              computing the hash function.
+
+       -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  asso-
+              ciated  value to be about 3 times larger than the
+              number of input keys". Conversely, a value of 1/3
+              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).
