Build Emacs-w64 with MSYS2/MinGW-w64 with Native Compilation

Instructions are modified from emacs-w64 Wiki page by zklhp. Many thanks for sharing!

1. Download the latest MSYS2 from this download page.

2. Install MSYS2 to, for example, C:\msys2 (make sure no space in path to avoid unwanted problems).

3. Optionally prettify the MSYS2 console mintty with ~/.minttyrc to make it more pleasing to eyes. Thanks to this awesome theme!

So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.
