Installation summary (The GNU Awk User’s Guide)

The gawk distribution is available from the GNU Project’s main distribution site, ftp.gnu.org. The canonical build recipe is:
```
wget https://ftp.gnu.org/gnu/gawk/gawk-5.1.0.tar.gz
tar -xvpzf gawk-5.1.0.tar.gz
cd gawk-5.1.0
./configure && make && make check
```
NOTE: Because of the ‘https://’ URL, you may have to supply the --no-check-certificate option to wget to download the file.
gawk may be built on non-POSIX systems as well. The currently supported systems are MS-Windows using MSYS, MSYS2, DJGPP, MinGW, and Cygwin, and both Vax/VMS and OpenVMS. Instructions for each system are included in this appendix.
Bug reports should be sent via email to bug-gawk@gnu.org. Bug reports should be in English and should include the version of gawk, how it was compiled, and a short program and data file that demonstrate the problem.
There are a number of other freely available awk implementations. Many are POSIX-compliant; others are less so.
