+Requirements
+------------
+You will need a C++ compiler and a C compiler.
+I use gcc 5.3.0 and 4.1.2, but the code should compile with any standards
+compliant compiler.
+Gcc is available at http://gcc.gnu.org.
+
+
+Procedure
+---------
+1. Unpack the archive if you have not done so already:
+
+	tar -xf arg_parser[version].tar.lz
+or
+	lzip -cd arg_parser[version].tar.lz | tar -xf -
+
+This creates the directory ./arg_parser[version] containing the source from
+the main archive.
+
+2. Change to arg_parser directory and run configure.
+   (Try 'configure --help' for usage instructions).
+
+	cd arg_parser[version]
+	./configure
+
+3. Run make.
+
+	make
+
+4. Optionally, type 'make check' to run the tests that come with arg_parser.
+
+5. Type 'make install' to install the program and any data files and
+   documentation.
+
+   Or type 'make install-compress', which additionally compresses the
+   info manual and the man page after installation. (Installing
+   compressed docs may become the default in the future).
+
+   You can install only the program, the info manual or the man page by
+   typing 'make install-bin', 'make install-info' or 'make install-man'
+   respectively.
+
+
+Another way
+-----------
+You can also compile arg_parser into a separate 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 '.', in '..' and
+in the directory that 'configure' is in.
+
+'configure' recognizes the option '--srcdir=DIR' to control where to
+look for the sources. Usually 'configure' can determine that directory
+automatically.
+
+After running 'configure', you can run 'make' and 'make install' as
+explained above.

+Description
+
+Arg_parser is an argument parser that follows POSIX and GNU conventions for
+command line arguments. There exist C++ and C versions of Arg_parser. The
+C++ version is implemented as a C++ class, while the C version is
+implemented as a single struct plus associated functions. Both are simpler,
+easier to use, and safer than 'getopt_long'.
+
+For maximum stability, Arg_parser is self-contained. It extracts all the
+information it needs from its arguments to avoid refering to them later.
+This avoids index-out-of-bounds errors.
+
+Arg_parser does not modify its arguments, nor uses any global variables. So
+you may create more than one parser in your program if you need or want to.
+
+The C++ version of Arg_parser can also parse options from configuration
+files.
+
+To use Arg_parser in your own programs simply copy the files 'arg_parser.h'
+and 'arg_parser.cc' (or 'carg_parser.h' and 'carg_parser.c' for the
+C version) in your source tree. See also the file 'main.cc' ('cmain.c') for
+an example of use.

+.SH NAME
+arg_parser \- test program for the Arg_parser argument parser
+.SH SYNOPSIS
+.B arg_parser
+[\fI\,options\/\fR]
+.SH DESCRIPTION
+Arg_parser \- POSIX/GNU command line argument parser. (C++ version)
+.PP
+Arg_parser is an argument parser that follows POSIX and GNU conventions for
+command line arguments. There exist C++ and C versions of Arg_parser. The
+C++ version is implemented as a C++ class, while the C version is
+implemented as a single struct plus associated functions. Both are simpler,
+easier to use, and safer than 'getopt_long'.
+.PP
+For maximum stability, Arg_parser is self\-contained. It extracts all the
+information it needs from its arguments to avoid refering to them later.
+This avoids index\-out\-of\-bounds errors.
+.PP
+Arg_parser does not modify its arguments, nor uses any global variables. So
+you may create more than one parser in your program if you need or want to.
+.PP
+The C++ version of Arg_parser can also parse options from configuration
+files.
+.PP
+To use Arg_parser in your own programs simply copy the files 'arg_parser.h'
+and 'arg_parser.cc' in your source tree. See also the file 'main.cc' for an
+example of use.

+1 Introduction
+**************
+
+Arg_parser is an argument parser that follows POSIX and GNU conventions
+for command line arguments. There exist C++ and C versions of
+Arg_parser. The C++ version is implemented as a C++ class, while the C
+version is implemented as a single struct plus associated functions.
+Both are simpler, easier to use, and safer than 'getopt_long'.
+
+   For maximum stability, Arg_parser is self-contained. It extracts all
+the information it needs from its arguments to avoid refering to them
+later.  This avoids index-out-of-bounds errors.
+
+   Arg_parser does not modify its arguments, nor uses any global
+variables. So you may create more than one parser in your program if
+you need or want to.
+
+   The C++ version of Arg_parser can also parse options from
+configuration files.

+
+2 Syntax of command line arguments
+**********************************
+
+POSIX recommends these conventions for command line arguments.
+'Arg_parser' makes it easy to implement them.
+
+   * A command line argument is a option if it begins with a hyphen
+     delimiter ('-').
+
+   * Multiple options may follow a hyphen delimiter in a single token
+     if the options don't take arguments. Thus, '-abc' is equivalent to
+     '-a -b -c'.
+
+   * Option names are single alphanumeric characters.
+
+   * Certain options require an argument.
+
+   * An option and its argument may or may not appear as separate
+     tokens. (In other words, the whitespace separating them is
+     optional).  Thus, '-o foo' and '-ofoo' are equivalent.
+
+   * Options typically precede other non-option arguments.
+
+     'Arg_parser' normally makes it appear as if all the option
+     arguments were specified before all the non-option arguments for
+     the purposes of parsing, even if the user of your program
+     intermixed option and non-option arguments. If you want the
+     arguments in the exact order the user typed them, call
+     'Arg_parser' with IN_ORDER = true.
+
+   * The argument '--' terminates all options; any following arguments
+     are treated as non-option arguments, even if they begin with a
+     hyphen.
+
+   * A token consisting of a single hyphen character is interpreted as
+     an ordinary non-option argument. By convention, it is used to
+     specify input from or output to the standard input and output
+     streams.
+
+   * Options may be supplied in any order, or appear multiple times.
+     The interpretation is left up to the particular application
+     program.
+
+   * GNU adds "long options" to these conventions. Long options consist
+     of '--' followed by a name made of alphanumeric characters and
+     hyphens. Option names are typically one to three words long, with
+     hyphens to separate words. Users can abbreviate the option names
+     as long as the abbreviations are unique.
+
+   * The syntax for optional option arguments is
+     '-<short_option><argument>' (without whitespace), or
+     '--<long_option>=<argument>'.

+3 Parsing arguments and reporting errors
+****************************************
+
+To use Arg_parser in your own programs first copy the files
+'arg_parser.h' and 'arg_parser.cc' in your source tree. See also the
+file 'main.cc' for an example of use.
+
+   The Arg_parser class has two constructors; one to parse command line
+arguments from ARGV, and the other to parse a single token from a
+configuration file or other source.
+
+ -- Data Type: struct Option
+     This structure describes a single option for the sake of
+     'Arg_parser'. The argument OPTIONS must be an array of these
+     structures, one for each option. Terminate the array with an
+     element containing a code which is zero.
+
+     'struct Option' has the following members:
+
+    'int code'
+          This member is the code that identifies the option, normally
+          the short-option character. Must be different from 0. A code
+          value outside the unsigned char range means a long-only
+          option.
+
+    'const char * name'
+          This member is the long option name. It is a zero-terminated
+          string. A null or empty name means a short-only option.
+
+    'enum Has_arg has_arg'
+          This member says whether the option takes an argument. It has
+          three valid values: 'no', 'yes' and 'maybe'.
+
+ -- Function: Arg_parser ( const int ARGC, const char * const ARGV[],
+          const Option OPTIONS[], const bool IN_ORDER = false )
+     Reads the arguments in ARGV and parses all options, option
+     arguments and non-option arguments contained in them. In case of
+     error, 'error().size()' will be non-zero.
+
+ -- Function: Arg_parser ( const char * const OPT, const char * const
+          ARG, const Option OPTIONS[] )
+     Restricted constructor. Parses a single token (plus an optional
+     second token in case an argument is needed for a parsed option).
+     Can be used to parse options from a configuration file one at a
+     time. Be warned that a single token may produce an undefined
+     number of short options. In case of error, 'error().size()' will
+     be non-zero.
+
+ -- Function: const std::string & error () const
+     Use this funtion to verify that the arguments have been correctly
+     parsed by the constructor. If there was an error parsing the
+     arguments, 'error' returns a non-empty error message explaining
+     the cause.
+
+
+File: arg_parser.info,  Node: Using Arg_parser,  Next: C version,  Prev: Initialization,  Up: Top
+
+4 Using the 'Arg_parser' class
+******************************
+
+After a successful call to the constructor, which must be verified by
+calling 'error', the parsed options and arguments can be accessed by
+means of the following functions:
+
+ -- Function: int arguments () const
+     This function returns the number of options and non-option
+     arguments parsed. This number is normally different from argc.
+
+ -- Function: int code ( const int I ) const
+     This function returns the code of the option at position I. Valid
+     values for I range from 0 to 'arguments() - 1'. If the returned
+     code is non-zero, 'argument(I)' is the option's argument (or is
+     empty if the option does not have an argument). If the returned
+     code is zero, 'argument(I)' is a non-option argument.
+
+ -- Function: const std::string & argument ( const int I ) const
+     This function returns the argument at position I. It may be the
+     argument of an option or a non-option argument, depending on the
+     value returned by 'code(I)'. Valid values for I range from 0 to
+     'arguments() - 1'.
+
+
+File: arg_parser.info,  Node: C version,  Next: Problems,  Prev: Using Arg_parser,  Up: Top
+
+5 Using the C version of Arg_parser
+***********************************
+
+To use the C version of Arg_parser in your own programs first copy the
+files 'carg_parser.h' and 'carg_parser.c' in your source tree.  See
+also the file 'cmain.c' for an example of use.
+
+   Then you need to declare a variable of type 'struct Arg_parser',
+pass its address to 'ap_init' to initialize it, and verify that
+'ap_error' returns 0.
+
+   'struct ap_Option' is identical to 'struct Option', except that
+'Has_arg' becomes 'ap_Has_arg', and the names of its three values are
+also prefixed with 'ap_'. *Note struct Option::, for details about the
+members.
+
+ -- Function: char ap_init ( struct Arg_parser * const AP, const int
+          ARGC, const char * const ARGV[], const struct ap_Option
+          OPTIONS[], const char IN_ORDER )
+     Reads the arguments in ARGV and parses all options, option
+     arguments and non-option arguments contained in them. Returns 0 if
+     there is not enough memory, else 1. In case of error, 'ap_error'
+     will return a non-null pointer.
+
+ -- Function: void ap_free ( struct Arg_parser * const AP )
+     Frees all dynamically allocated data structures.
+
+ -- Function: const char * ap_error ( const struct Arg_parser * const
+          AP )
+     Use this funtion to verify that the arguments have been correctly
+     parsed by 'ap_init'. If there was an error parsing the arguments,
+     'ap_error' returns a pointer to an error message explaining the
+     cause, else it returns a null pointer.
+
+   After a successful call to 'ap_init', which must be verified by
+calling 'ap_error', the parsed options and arguments can be accessed by
+means of the following functions:
+
+ -- Function: int ap_arguments ( const struct Arg_parser * const AP )
+     This function returns the number of options and non-option
+     arguments parsed. This number is normally different from argc.
+
+ -- Function: int ap_code ( const struct Arg_parser * const AP, const
+          int I )
+     This function returns the code of the option at position I. Valid
+     values for I range from 0 to 'ap_arguments() - 1'. If the returned
+     code is non-zero, 'ap_argument(I)' is the option's argument (or is
+     empty if the option does not have an argument). If the returned
+     code is zero, 'ap_argument(I)' is a non-option argument.
+
+ -- Function: const char * ap_argument ( const struct Arg_parser *
+          const AP, const int I )
+     This function returns the argument at position I. It may be the
+     argument of an option or a non-option argument, depending on the
+     value returned by 'ap_code(I)'. Valid values for I range from 0 to
+     'ap_arguments() - 1'.
+
+   When you are finished, you should free all dynamically allocated data
+structures by calling 'ap_free'.

+Arg_parser is an argument parser that follows POSIX and GNU conventions for
+command line arguments. There exist C++ and C versions of Arg_parser. The

+POSIX recommends these conventions for command line arguments.
+@code{Arg_parser} makes it easy to implement them.
+
+@itemize @bullet
+@item A command line argument is a option if it begins with a hyphen
+delimiter (@code{-}).
+
+@item Multiple options may follow a hyphen delimiter in a single token
+if the options don't take arguments. Thus, @code{-abc} is equivalent to
+@w{@code{-a -b -c}}.
+
+@item Option names are single alphanumeric characters.
+
+@item Certain options require an argument.
+
+@item An option and its argument may or may not appear as separate
+tokens. (In other words, the whitespace separating them is optional).
+Thus, @w{@code{-o foo}} and @code{-ofoo} are equivalent.
+
+@item Options typically precede other non-option arguments.
+
+@code{Arg_parser} normally makes it appear as if all the option
+arguments were specified before all the non-option arguments for the
+purposes of parsing, even if the user of your program intermixed option
+and non-option arguments. If you want the arguments in the exact order
+the user typed them, call @code{Arg_parser} with @var{in_order} = true.
+
+@item The argument @code{--} terminates all options; any following
+arguments are treated as non-option arguments, even if they begin with a
+hyphen.
+
+@item A token consisting of a single hyphen character is interpreted as
+an ordinary non-option argument. By convention, it is used to specify
+input from or output to the standard input and output streams.
+
+@item Options may be supplied in any order, or appear multiple times.
+The interpretation is left up to the particular application program.
+
+@item GNU adds @dfn{long options} to these conventions. Long options
+consist of @code{--} followed by a name made of alphanumeric characters
+and hyphens. Option names are typically one to three words long, with
+hyphens to separate words. Users can abbreviate the option names as long
+as the abbreviations are unique.
+

+@code{-<short_option><argument>} (without whitespace), or
+@code{--<long_option>=<argument>}.

+.SH NAME
+arg_parser \- test program for the Arg_parser argument parser
+.SH SYNOPSIS
+.B carg_parser
+[\fI\,options\/\fR]
+.SH DESCRIPTION
+Arg_parser \- POSIX/GNU command line argument parser. (C version)
+.PP
+Arg_parser is an argument parser that follows POSIX and GNU conventions for
+command line arguments. There exist C++ and C versions of Arg_parser. The
+C++ version is implemented as a C++ class, while the C version is
+implemented as a single struct plus associated functions. Both are simpler,
+easier to use, and safer than 'getopt_long'.
+.PP
+For maximum stability, Arg_parser is self\-contained. It extracts all the
+information it needs from its arguments to avoid refering to them later.
+This avoids index\-out\-of\-bounds errors.
+.PP
+Arg_parser does not modify its arguments, nor uses any global variables. So
+you may create more than one parser in your program if you need or want to.
+.PP
+The C++ version of Arg_parser can also parse options from configuration
+files.
+.PP
+To use Arg_parser in your own programs simply copy the files 'carg_parser.h'
+and 'carg_parser.c' in your source tree. See also the file 'cmain.c' for an
+example of use.
