+.SH NAME
+bison \- GNU Project parser generator (yacc replacement)
+.SH SYNOPSIS
+.B bison
+[\fI\,OPTION\/\fR]... \fI\,FILE\/\fR
+.SH DESCRIPTION
+.I Bison
+is a parser generator in the style of
+.IR yacc (1).
+It should be upwardly compatible with input files designed
+for
+.IR yacc .
+.PP
+Input files should follow the
+.I yacc
+convention of ending in
+.BR .y .
+Unlike
+.IR yacc ,
+the generated files do not have fixed names, but instead use the prefix
+of the input file.
+Moreover, if you need to put
+.I C++
+code in the input file, you can end his name by a C++-like extension
+(.ypp or .y++), then bison will follow your extension to name the
+output file (.cpp or .c++).
+For instance, a grammar description file named
+.B parse.yxx
+would produce the generated parser in a file named
+.BR parse.tab.cxx ,
+instead of
+.IR yacc 's
+.B y.tab.c
+or old
+.I Bison
+version's
+.BR parse.tab.c .
+.PP
+This description of the options that can be given to
+.I bison
+is adapted from the node
+.B Invocation
+in the
+.B bison.texi
+manual, which should be taken as authoritative.
+.PP
+.I Bison
+supports both traditional single-letter options and mnemonic long
+option names.  Long option names are indicated with
+.B \-\-
+instead of
+.BR \- .
+Abbreviations for option names are allowed as long as they
+are unique.  When a long option takes an argument, like
+.BR \-\-file-prefix ,
+connect the option name and the argument with
+.BR = .
+.PP
+Generate a deterministic LR or generalized LR (GLR) parser employing
+LALR(1), IELR(1), or canonical LR(1) parser tables.  IELR(1) and
+canonical LR(1) support is experimental.
+.PP
+Mandatory arguments to long options are mandatory for short options too.
+The same is true for optional arguments.
