== SPKG directory structure ==

 * src directory: '''vanilla''' upstream, but there are a few exceptions
 * SPKG.txt: describes the spkg in wiki format, each new revision needs an updated changelog entry or an automatic "needs work" at review time
 * spkg-install: the install script - see below for an example and some style tips
 * spkg-check: runs the test suite - this is somewhat optional since not all spkgs have test suites. If possible do create such a script since it helps isolate bugs in upstream packages
 * patches: for patches against upstream. Each file foo.extension needs to have a diff against the original file, i.e. foo.extension.patch for easy rebases against new upstream. Updated files should be copied into the right place in src at the start of spkg-install. Please document all patches in SPKG.txt, i.e. what they do, if they are platform specific, if they should be pushed upstream

== Important things to consider ==

There are usually a number of things to do for all spkgs:

 * ensure that "make install" is non-parallel, i.e. do a "export MAKE=make"
 * SAGE_LOCAL check (#633)
 * add spkg-check (#299)
 * add proper SPKG.txt to all packages
 * /usr/bin/env bash (#1638)
 * add md5sums for spkgs (#329)
 * set LDFLAGS on OSX (#3349)

== A Sample spkg-install ==
{{{
#!/usr/bin/env bash

if [ "$SAGE_LOCAL" = "" ]; then
   echo "SAGE_LOCAL undefined ... exiting";
   echo "Maybe run 'sage -sh'?"
   exit 1
fi

cd src

./configure --prefix="$SAGE_LOCAL"
if [ $? -ne 0 ]; then
   echo "Error configuring PACKAGE_NAME."
   exit 1
fi

make
if [ $? -ne 0 ]; then
   echo "Error building PACKAGE_NAME."
   exit 1
fi

make install
if [ $? -ne 0 ]; then
   echo "Error installing PACKAGE_NAME."
   exit 1
fi
}}}
