Resets the position of the file pointer to the point created the GzipReader object. The associated IO object needs to respond to the seek method.
See Zlib::GzipReader documentation for a description.
Reads at most maxlen bytes from the gziped stream but it blocks only if gzipreader has no data immediately available. If the optional outbuf argument is present, it must reference a String, which will receive the data. It raises EOFError on end of file.

Returns true if stat is readable by the effective user id of this process.
File.stat("testfile").readable? #=> true
Returns true if stat has its sticky bit set, false if it doesn’t or if the operating system doesn’t support this feature.
File.stat("testfile").sticky? #=> false
Returns an Array with 14 elements representing the instruction sequence with the following data:
A string identifying the data format. Always YARVInstructionSequence/SimpleDataFormat.
The major version of the instruction sequence.
The minor version of the instruction sequence.
A number identifying the data format. Always 1.
A hash containing:
:arg_size
the total number of arguments taken by the method or the block (0 if iseq doesn’t represent a method or block)
:local_size
the number of local variables + 1
:stack_max
used in calculating the stack depth at which a SystemStackError is thrown.
label
The name of the context (block, method, class, module, etc.) that this instruction sequence belongs to.
<main> if it’s at the top level, <compiled> if it was evaluated from a string.
path
The relative path to the Ruby file where the instruction sequence was loaded from.
<compiled> if the iseq was evaluated from a string.
absolute_path
The absolute path to the Ruby file where the instruction sequence was loaded from.
nil if the iseq was evaluated from a string.
first_lineno
The number of the first source line where the instruction sequence was loaded from.
The type of the instruction sequence.
Valid values are :top, :method, :block, :class, :rescue, :ensure, :eval, :main, and plain.
An array containing the names of all arguments and local variables as symbols.
An Hash object containing parameter information.
More info about these values can be found in vm_core.h.
A list of exceptions and control flow operators (rescue, next, redo, break, etc.).
An array of arrays containing the instruction names and operands that make up the body of the instruction sequence.
Note that this format is MRI specific and version dependent.
Returns the contents of this Tms object as a formatted string, according to a format string like that passed to Kernel.format. In addition, format accepts the following extensions:
%u
Replaced by the user CPU time, as reported by Tms#utime.
%y
Replaced by the system CPU time, as reported by stime (Mnemonic: y of “s*y*stem”)
%U
Replaced by the children’s user CPU time, as reported by Tms#cutime
%Y
Replaced by the children’s system CPU time, as reported by Tms#cstime
%t
Replaced by the total CPU time, as reported by Tms#total
%r
Replaced by the elapsed real time, as reported by Tms#real
%n
Replaced by the label string, as reported by Tms#label (Mnemonic: n of “*n*ame”)
If format is not given, FORMAT is used as default value, detailing the user, system and real elapsed time.
Same as format.
Returns a new 6-element array, consisting of the label, user CPU time, system CPU time, children’s user CPU time, children’s system CPU time and elapsed real time.
A list of authors for this gem.
Alternatively, a single author can be specified by assigning a string to ‘spec.author`
Usage:
spec.authors = ['John Jones', 'Mary Smith']
The platform this gem runs on.
This is usually Gem::Platform::RUBY or Gem::Platform::CURRENT.
Most gems contain pure Ruby code; they should simply leave the default value in place. Some gems contain C (or other) code to be compiled into a Ruby “extension”. The gem should leave the default value in place unless the code will only compile on a certain type of system. Some gems consist of pre-compiled code (“binary gems”). It’s especially important that they set the platform attribute appropriately. A shortcut is to set the platform to Gem::Platform::CURRENT, which will cause the gem builder to set the platform to the appropriate value for the system on which the build is being performed.
If this attribute is set to a non-default value, it will be included in the filename of the gem when it is built such as: nokogiri-1.6.0-x86-mingw32.gem
Usage:
spec.platform = Gem::Platform.local
Returns a Gem::StubSpecification for every installed gem
Reset the list of known specs, running pre and post reset hooks registered in Gem.
Abbreviate the spec for downloading. Abbreviated specs are only used for searching, downloading and related activities and do not need deployment specific information (e.g. list of files). So we abbreviate the spec, making it much smaller for quicker downloads.
Singular reader for authors. Returns the first author in the list
The list of author names who wrote this gem.
spec.authors = ['Chad Fowler', 'Jim Weirich', 'Rich Kilmer']
Normalize the list of files so that:
All file lists have redundancies removed.
Files referenced in the extra_rdoc_files are included in the package file list.
The platform this gem runs on. See Gem::Platform for details.
