Fixed a link to library docs and silenced b2 warning about unescaped character.

Updated check for apt-add-repository capabilities.
In Ubuntu 20.04 there appeared an updated version of the software-properties-common package in focal-updates, which ships a newer apt-add-repository version that doesn't support -P/-S/-U command line arguments. Since we cannot rely on package version checks to determine apt-add-repository capabilities, we have to parse its --help output instead. Also, made source list processing more protected against spaces.

+# Boost.Iterator
+
+Boost.Iterator, part of collection of the [Boost C++ Libraries](https://github.com/boostorg), provides tools for building and working with iterators in C++. The library also provides a number of iterator classes that can be used out of the box.
+
+### Directories
+
+* **doc** - Documentation sources
+* **include** - Interface headers of Boost.Iterator
+* **test** - Boost.Iterator unit tests
+* **example** - Boost.Iterator usage examples
+
+### More information
+
+* [Documentation](https://boost.org/libs/iterator)
+* [Report bugs](https://github.com/boostorg/iterator/issues/new). Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
+* Submit your patches as [pull requests](https://github.com/boostorg/iterator/compare) against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](https://www.boost.org/LICENSE_1_0.txt).

Andrey Semashev	5ebbe941be	Updated check for apt-add-repository capabilities. In Ubuntu 20.04 there appeared an updated version of the software-properties-common package in focal-updates, which ships a newer apt-add-repository version that doesn't support -P/-S/-U command line arguments. Since we cannot rely on package version checks to determine apt-add-repository capabilities, we have to parse its --help output instead. Also, made source list processing more protected against spaces.	2021-11-16 00:48:57 +03:00

Edward Diener	987151dde6	[skip ci] Add "cxxstd" json field. The "cxxstd" json field is being added to each Boost library's meta json information for libraries in order to specify the minumum C++ standard compilation level. The value of this field matches one of the values for 'cxxstd' in Boost.Build. The purpose of doing this is to provide information for the Boost website documentation for each library which will specify the minimum C++ standard compilation that an end-user must employ in order to use the particular library. This will aid end-users who want to know if they can successfully use a Boost library based on their C++ compiler's compilation level, without having to search the library's documentation to find this out.	2021-01-19 23:19:27 -05:00
