+\f1 \expnd0\expndtw0\kerning0
+ is extremely fast and scalable systems and configuration management software for predictive orchestration, cloud and data center automation, server provisioning, application deployment and more. \
+Documentation for Salt is available at {\field{\*\fldinst{HYPERLINK "http://docs.saltstack.com/"}}{\fldrslt \cf2 \ul \ulc2 http://docs.saltstack.com}} \
+This package will install Salt on your Mac. Salt installs into 
+\f2\fs22 /opt/salt
+\f1\fs24 .\
+Sample configuration files (
+\f2\fs22 master.dist
+\f1\fs24  and 
+\f2\fs22 minion.dist
+\f1\fs24 ) will be installed to 
+\f2\fs22 /etc/salt
+\f1\fs24 . Create copies of them without the '
+\f2\fs22 .dist
+\f1\fs24 ' in the filename and edit as you see fit.\
+This Salt package uses a custom-built Python. To install additional Python modules for Salt, use the associated 'pip' binary. For example, if you need LDAP support in Salt you will need the 'python-ldap' module. Install it with 
+\f2\fs22 /opt/salt/bin/pip install python-ldap
+\f1\fs24 \
+Note that some Python modules need a compiler available. Installing Apple's Xcode Command Line Tools should provide the necessary utilities. Alternatively, {\field{\*\fldinst{HYPERLINK "http://macports.org/"}}{\fldrslt \cf2 \ul \ulc2 MacPorts}}, {\field{\*\fldinst{HYPERLINK "http://finkproject.org/"}}{\fldrslt \cf2 \ul \ulc2 Fink}}, or {\field{\*\fldinst{HYPERLINK "http://brew.sh/"}}{\fldrslt \cf2 \ul \ulc2 Homebrew}} may provide what you need.}
