| The library have been under way for a long time. Dietmar Kühl originally intended |
| to submit an <code class="computeroutput"><span class="identifier">array_traits</span></code> class |
| template which had most of the functionality present now, but only for arrays |
| and standard containers. |
| </p> |
| <p> |
| Meanwhile work on algorithms for containers in various contexts showed the |
| need for handling pairs of iterators, and string libraries needed special treatment |
| of character arrays. In the end it made sense to formalize the minimal requirements |
| of these similar concepts. And the results are the Range concepts found in |
| this library. |
| </p> |
| <p> |
| The term Range was adopted because of paragraph 24.1/7 from the C++ standard: |
| </p> |
| <p> |
| Most of the library's algorithmic templates that operate on data structures |
| have interfaces that use ranges. A range is a pair of iterators that designate |
| the beginning and end of the computation. A range [i, i) is an empty range; |
| in general, a range [i, j) refers to the elements in the data structure starting |
| with the one pointed to by i and up to but not including the one pointed to |
| by j. Range [i, j) is valid if and only if j is reachable from i. The result |
| of the application of functions in the library to invalid ranges is undefined. |

| </h4> |
| <p> |
| This version introduced Range Adaptors and Range Algorithms. This version 2 |
| is the result of a merge of all of the RangeEx features into Boost.Range. |
| </p> |
| <p> |
| There were an enormous number of very significant contributors through all |
| stages of this library. |
| </p> |
| <p> |
| Prior to Boost.RangeEx there had been a number of Range library implementations, |
| these include library implementations by Eric Niebler, Adobe, Shunsuke Sogame |
| etc. Eric Niebler contributed the Range Adaptor idea which is arguably the |
| single biggest innovation in this library. Inevitably a great deal of commonality |
| evolved in each of these libraries, but a considerable amount of effort was |
| expended to learn from all of the divergent techniques. |
| </p> |

| user feedback, design suggestions, or defect detection: |
