Mostly this is just changing http: to https:.
In one or two places it removes no-longer-useful URLs.

This gives some notes on obtaining the tools required for development.
I.E. the tools checked for by the bootstrap script and include:
- Autoconf <https://www.gnu.org/software/autoconf/>
- Automake <https://www.gnu.org/software/automake/>
- Bison <https://www.gnu.org/software/bison/>
- Gettext <https://www.gnu.org/software/gettext/>
- Git <https://git-scm.com/>
- Gperf <https://www.gnu.org/software/gperf/>
- Gzip <https://www.gnu.org/software/gzip/>
- Perl <https://www.cpan.org/>
- Pkg-config <https://www.freedesktop.org/wiki/Software/pkg-config/>
- Rsync <https://rsync.samba.org/>
- Tar <https://www.gnu.org/software/tar/>
- Texinfo <https://www.gnu.org/software/texinfo/>
Note please try to install/build official packages for your system.
If these programs are not available use the following instructions
to build them and install the results into a directory that you will
then use when building this package.
Even if the official version of a package for your system is too old,
please install it, as it may be required to build the newer versions.
The examples below install into $HOME/grep/deps/, so if you are
going to follow these instructions, first ensure that your $PATH is
set correctly by running this command:
prefix=$HOME/grep/deps
export PATH=$prefix/bin:$PATH
* autoconf *
# Note Autoconf 2.62 or newer is needed to build automake-1.11.1
git clone --depth=1 git://git.sv.gnu.org/autoconf.git
git checkout v2.62
autoreconf -vi
./configure --prefix=$prefix
make install
* automake *
# Note help2man is required to build automake fully
git clone git://git.sv.gnu.org/automake.git
cd automake
git checkout v1.11.1
./bootstrap
./configure --prefix=$prefix
make install
This package uses XZ utils (successor to LZMA) to create
a compressed distribution tarball. Using this feature of Automake
requires version 1.10a or newer, as well as the xz program itself.
* xz *
git clone git://ctrl.tukaani.org/xz.git
cd xz
./autogen.sh
./configure --prefix=$prefix
make install
Now you can build this package as described in README-hacking.
