+
+```
+ conf.gem :github => 'iij/mruby-pack'
+```
+
+There is no dependency on other mrbgems.
+
+
+## Supported template string
+ - A : arbitrary binary string (space padded, count is width)
+ - a : arbitrary binary string (null padded, count is width)
+ - C : 8-bit unsigned (unsigned char)
+ - c : 8-bit signed (signed char)
+ - D, d: 64-bit float, native format
+ - E : 64-bit float, little endian byte order
+ - e : 32-bit float, little endian byte order
+ - F, f: 32-bit float, native format
+ - G : 64-bit float, network (big-endian) byte order
+ - g : 32-bit float, network (big-endian) byte order
+ - H : hex string (high nibble first)
+ - h : hex string (low nibble first)
+ - I : unsigned integer, native endian (`unsigned int` in C)
+ - i : signed integer, native endian (`int` in C)
+ - L : 32-bit unsigned, native endian (`uint32_t`)
+ - l : 32-bit signed, native endian (`int32_t`)
+ - m : base64 encoded string (see RFC 2045, count is width)
+ - N : 32-bit unsigned, network (big-endian) byte order
