(description
|
||||
"Flex is a tool for generating scanners. A scanner, sometimes
|
||||
called a tokenizer, is a program which recognizes lexical patterns in
|
||||
text. The flex program reads user-specified input files, or its standard
|
||||
input if no file names are given, for a description of a scanner to
|
||||
generate. The description is in the form of pairs of regular expressions
|
||||
and C code, called rules. Flex generates a C source file named,
|
||||
\"lex.yy.c\", which defines the function yylex(). The file \"lex.yy.c\"
|
||||
can be compiled and linked to produce an executable. When the executable
|
||||
is run, it analyzes its input for occurrences of text matching the
|
||||
regular expressions for each rule. Whenever it finds a match, it
|
||||
executes the corresponding C code.")

The `test-bison-yyl{loc,val}' tests fail with "conflicting types for

'testparse'" because `YYPARSE_PARAM' is undefined; work around that.
