The ./configure command in README.md's Building Documentation section was
missing the $ prefix. Add the prefix to be consistent with other commands in the
document.
The LLVM build system is somewhat picky about which Python is used to build it
as it's known to be incompatible with the default `python2` package that ships
with MinGW. This was previously detected for MSVC builds but the logic was left
out for MinGW by accident (now that we've switched to cmake builds for LLVM
everywhere).
This corrects the `./configure` check and also updates the `README.md`
accordingly. Additionally, a number of instructions were updated to work with
the most recent copy of MSYS2.
Closes#34489
http://mingw-w64.org/doku.php/download/mingw-builds now provides GCC 5.x as a default version, but avoiding 5.x is exactly the reason why Mingw-builds is recommended instead of MSYS2's own mingw toolchain. One of the 4.9.x versions has to manually chosen during installation.
In other words, enforce what was documented in #30626 (and also stop blaming it on LLVM, we have at least one Python script of our own).
Also, there is no Python later than 2.7 and there never will be.
Running `/usr/bin/time -v make` to build rust (using local llvm) shows the maximum memory usage at 715 megabytes on 32-bit x86 (on arm linux it's even less @ 580M).
Reworded according to @brson's input.
This PR adds a note to the end of the Windows build instructions to reflect the issues detailed in #28260, as well as a work around using older versions of gcc. I've avoided going into detail as I did not wish to bloat the README, and so that the changes are easy to yank once the issue is resolved.
Remove leading newlines; replace lines containing only whitespace with empty lines; replace multiple trailing newlines with a single newline; remove trailing whitespace in lines
Encountered an issue going through the guide for installing the `mingw` toolchain on Windows with msys2, after some googling I found the [solution](https://github.com/Alexpux/MSYS2-packages/issues/163#issuecomment-73555971) and thought it would be good to update the README so people don't get frustrated. :)
- Various grammatical changes.
- Use triple-backtick syntax and sh highlighting for code blocks.
- Fix indentation of code block in step 2 of "Building on Windows".
- Use title case for "Getting Help" subheading.
This redux of CONTRIBUTING.md adds in more information, including
subsuming both compliment-bugreport.md and Note-development-policy
in the wiki.
I only glanced at the broad TOC of Note-development-policy, and did
not use the text as the basis for the re-write. This will then address
the last outstanding part of #5831.
There's only one build-critical path in which perl is used, and it was to do a text replacement trivially achievable with sed(1).
I ported the indenter script because it [appears to be used][indenter], but removed check links because it appears to be entirely out of date.

This pulls all of our long-form documentation into a single document,
nicknamed "the book" and formally titled "The Rust Programming
Language."
A few things motivated this change:
* People knew of The Guide, but not the individual Guides. This merges
them together, helping discoverability.
* You can get all of Rust's longform documentation in one place, which
is nice.
* We now have rustbook in-tree, which can generate this kind of
documentation. While its style is basic, the general idea is much
better: a table of contents on the left-hand side.
* Rather than a almost 10,000-line guide.md, there are now smaller files
per section.
The Windows-specific instruction under 'Quick Start' linked the wiki article on getting started developing Rust itself, but the quick start is just about obtaining a working Rust installation. The actual wiki page with Windows-specific instructions was difficult to find.
The most important thing to note on Windows is that you need mingw-builds, and it is totally not obvious. The only place where I have seen it mentioned is the wiki page, which was difficult to find before.

The Guide isn't 100% perfect, but it's basically complete. It's
certainly better than the tutorial is. Time to start pointing more
people its way.
I also just made it consistent to call all things 'guides' rather than
tutorials.
Fixes#9874. This is the big one.
And two bugs that just go away.
Fixes#14503.
Fixes#15009.
Update the instructions to reflect that we have binary installers for all
supported platforms, and move the building from source directions into a
dedicated "Building from Source" directory.
