* call-seq:
* Dir.glob( pattern, [flags], [base: path] ) -> array
* Dir.glob( pattern, [flags], [base: path] ) { |filename| block } -> nil
*
* Expands +pattern+, which is a pattern string or an Array of pattern
* strings, and returns an array containing the matching filenames.
* If a block is given, calls the block once for each matching filename,
* passing the filename as a parameter to the block.
*
* The optional +base+ keyword argument specifies the base directory for
* interpreting relative pathnames instead of the current working directory.
* As the results are not prefixed with the base directory name in this
* case, you will need to prepend the base directory name if you want real
* paths.
*
* Note that the pattern is not a regexp, it's closer to a shell glob.
* See File::fnmatch for the meaning of the +flags+ parameter.
* Case sensitivity depends on your system (File::FNM_CASEFOLD is ignored),
* as does the order in which the results are returned.
*
* <code>*</code>::
* Matches any file. Can be restricted by other values in the glob.
* Equivalent to <code>/ .* /mx</code> in regexp.
*
* <code>*</code>:: Matches all files
* <code>c*</code>:: Matches all files beginning with <code>c</code>
* <code>*c</code>:: Matches all files ending with <code>c</code>
* <code>\*c\*</code>:: Match all files that have <code>c</code> in them
* (including at the beginning or end).
*
* Note, this will not match Unix-like hidden files (dotfiles). In order
* to include those in the match results, you must use the
* File::FNM_DOTMATCH flag or something like <code>"{*,.*}"</code>.
*
* <code>**</code>::
* Matches directories recursively.
*
* <code>?</code>::
* Matches any one character. Equivalent to <code>/.{1}/</code> in regexp.
*
* <code>[set]</code>::
* Matches any one character in +set+. Behaves exactly like character sets
* in Regexp, including set negation (<code>[^a-z]</code>).
*
* <code>{p,q}</code>::
* Matches either literal <code>p</code> or literal <code>q</code>.
* Equivalent to pattern alternation in regexp.
*
* Matching literals may be more than one character in length. More than
* two literals may be specified.
*
* <code> \\ </code>::
* Escapes the next metacharacter.
*
* Note that this means you cannot use backslash on windows as part of a
* glob, i.e. <code>Dir["c:\\foo*"]</code> will not work, use
* <code>Dir["c:/foo*"]</code> instead.
*
* Examples:
*
* Dir["config.?"] #=> ["config.h"]
* Dir.glob("config.?") #=> ["config.h"]
* Dir.glob("*.[a-z][a-z]") #=> ["main.rb"]
* Dir.glob("*.[^r]*") #=> ["config.h"]
* Dir.glob("*.{rb,h}") #=> ["main.rb", "config.h"]
* Dir.glob("*") #=> ["config.h", "main.rb"]
* Dir.glob("*", File::FNM_DOTMATCH) #=> [".", "..", "config.h", "main.rb"]
* Dir.glob(["*.rb", "*.h"]) #=> ["main.rb", "config.h"]
*
* rbfiles = File.join("**", "*.rb")
* Dir.glob(rbfiles) #=> ["main.rb",
* # "lib/song.rb",
* # "lib/song/karaoke.rb"]
*
* Dir.glob(rbfiles, base: "lib") #=> ["song.rb",
* # "song/karaoke.rb"]
*
* libdirs = File.join("**", "lib")
* Dir.glob(libdirs) #=> ["lib"]
*
* librbfiles = File.join("**", "lib", "**", "*.rb")
* Dir.glob(librbfiles) #=> ["lib/song.rb",
* # "lib/song/karaoke.rb"]
*
* librbfiles = File.join("**", "lib", "*.rb")

* Returns true if +path+ matches against +pattern+. The pattern is not a

*
* <code>*</code>::
* Matches any file. Can be restricted by other values in the glob.
* Equivalent to <code>/ .* /x</code> in regexp.
*
* <code>*</code>:: Matches all files regular files
* <code>c*</code>:: Matches all files beginning with <code>c</code>
* <code>*c</code>:: Matches all files ending with <code>c</code>
* <code>\*c*</code>:: Matches all files that have <code>c</code> in them
* (including at the beginning or end).
*
* To match hidden files (that start with a <code>.</code> set the
* File::FNM_DOTMATCH flag.
*
* <code>**</code>::
* Matches directories recursively or files expansively.
*
* <code>?</code>::
* Matches any one character. Equivalent to <code>/.{1}/</code> in regexp.
*
* <code>[set]</code>::
* Matches any one character in +set+. Behaves exactly like character sets
* in Regexp, including set negation (<code>[^a-z]</code>).
*
* <code> \ </code>::
* Escapes the next metacharacter.
*
* <code>{a,b}</code>::
* Matches pattern a and pattern b if File::FNM_EXTGLOB flag is enabled.
* Behaves like a Regexp union (<code>(?:a|b)</code>).
*
* +flags+ is a bitwise OR of the <code>FNM_XXX</code> constants. The same
* glob pattern and flags are used by Dir::glob.
