If you prefer a manual installation, please use the following instructions:
$ git clone git://github.com/petervanderdoes/gitflow.git
Then, you can install git-flow, using:
$ sudo make install
By default, git-flow will be installed in /usr/local. To change the prefix where git-flow will be installed, simply specify it explicitly, using:
$ sudo make prefix=/opt/local install
This will install git-flow in /opt/local/bin
git-flow depends on the availability of the command line utility getopt,
which may not be available in your Unix/Linux environment.
Please use your favorite package manager to install getopt.
For Cygwin, install the util-linux package to get getopt.
If you use apt-get as your install manager, the package name is opt.
