# Important Build-Time Environment Variables (see name-defines.inc)
# NO_PACKAGE=1    -> Do Not Build/Rebuild Package RPM
# NO_MODULEFILE=1 -> Do Not Build/Rebuild Modulefile RPM
#
# Important Install-Time Environment Variables (see post-defines.inc)
# VERBOSE=1       -> Print detailed information at install time
# RPM_DBPATH      -> Path To Non-Standard RPM Database Location
#
# Typical Command-Line Example:
# ./build_rpm.sh Bar.spec
# cd ../RPMS/x86_64
# rpm -i --relocate /tmprpm=/opt/apps Bar-package-1.1-1.x86_64.rpm
# rpm -i --relocate /tmpmod=/opt/apps Bar-modulefile-1.1-1.x86_64.rpm
# rpm -e Bar-package-1.1-1.x86_64 Bar-modulefile-1.1-1.x86_64

Summary: A Nice little relocatable skeleton spec file example.

# Give the package a base name
%define pkg_base_name git
%define MODULE_VAR    GIT

# Create some macros (spec file variables)
%define major_version 2
%define minor_version 6
%define micro_version 3

%define pkg_version %{major_version}.%{minor_version}.%{micro_version}

Git is a free and open source distributed version control system designed to
handle everything from small to very large projects with speed and efficiency.
Git is easy to learn and has a tiny footprint with lightning fast performance.

The %{MODULE_VAR} module file defines the following environment variables:
TACC_%{MODULE_VAR}_DIR, TACC_%{MODULE_VAR}_BIN, TACC_%{MODULE_VAR}_LIB for the
location of the %{MODULE_VAR} distribution, binaries, and libraries
respectively. GIT_EXEC_PATH, which is also defined, determines where Git looks
for its sub-programs. You can check the current setting by running
"git --exec-path".
