+      analysis, graphical facilities for data analysis and display
+      either on-screen or on hardcopy, and a well-developed, simple and

+      A Package for Analyzing Lattice Polytopes (PALP) is a set of C
+      programs for calculations with lattice polytopes and applications to
+      toric geometry.
+
+      It contains routines for vertex and facet enumeration, computation of
+      incidences and symmetries, as well as completion of the set of lattice
+      points in the convex hull of a given set of points. In addition, there
+      are procedures specialised to reflexive polytopes such as the
+      enumeration of reflexive subpolytopes, and applications to toric
+      geometry and string theory, like the computation of Hodge data and
+      fibration structures for toric Calabi-Yau varieties.  The package is
+      well tested and optimised in speed as it was used for time consuming
+      tasks such as the classification of reflexive polyhedra in 4
+      dimensions and the creation and manipulation of very large lists of
+      5-dimensional polyhedra.
+
+      While originally intended for low-dimensional applications, the
+      algorithms work in any dimension and our key routine for vertex and
+      facet enumeration compares well with existing packages.

+       PARI/GP is a widely used computer algebra system designed for fast
+       computations in number theory (factorizations, algebraic number theory,
+       elliptic curves...), but also contains a large number of other useful
+       functions to compute with mathematical entities such as matrices,
+       polynomials, power series, algebraic numbers etc., and a lot of
+       transcendental functions. PARI is also available as a C library to allow
+       for faster computations.
+
+       Originally developed by Henri Cohen and his co-workers (Université
+       Bordeaux I, France), PARI is now under the GPL and maintained by Karim
+       Belabas with the help of many volunteer contributors.
+
+       - PARI is a C library, allowing fast computations.
+       - gp is an easy-to-use interactive shell giving access to the
+          PARI functions.
+       - GP is the name of gp's scripting language.
+       - gp2c, the GP-to-C compiler, combines the best of both worlds
+          by compiling GP scripts to the C language and transparently loading
+          the resulting functions into gp. (gp2c-compiled scripts will typically
+          run 3 or 4 times faster.) gp2c currently only understands a subset
+           of the GP language.

+# Sage on nixos
+
+Sage is a pretty complex package that depends on many other complex packages and patches some of those. As a result, the sage nix package is also quite complex.
+
+Don't feel discouraged to fix, simplify or improve things though. The individual files have comments explaining their purpose. The most importent ones are `default.nix` linking everything together, `sage-src.nix` adding patches and `sagelib.nix` building the actual sage package.
+
+## The sage build is broken
+
+First you should find out which change to nixpkgs is at fault (if you don't already know). You can use `git-bisect` for that (see the manpage).
+
+If the build broke as a result of a package update, try those solutions in order:
+
+- search the [sage trac](https://trac.sagemath.org/) for keywords like "Upgrade <package>". Maybe somebody has already proposed a patch that fixes the issue. You can then add a `fetchpatch` to `sage-src.nix`.
+
+- check if [gentoo](https://github.com/cschwan/sage-on-gentoo/tree/master/sci-mathematics/sage), [debian](https://salsa.debian.org/science-team/sagemath/tree/master/debian) or [arch linux](https://git.archlinux.org/svntogit/community.git/tree/trunk?h=packages/sagemath) already solved the problem. You can then again add a `fetchpatch` to `sage-src.nix`. If applicable you should also [propose the patch upstream](#proposing-a-sage-patch).
+
+- fix the problem yourself. First clone the sagemath source and then check out the sage version you want to patch:
+
+```
+[user@localhost ~]$ git clone git://github.com/sagemath/sage.git
+[user@localhost ~]$ cd sage
+[user@localhost sage]$ git checkout 8.2 # substitute the relevant version here
+```
+
+Then make the needed changes and generate a patch with `git diff`:
+
+```
+[user@localhost ~]$ <make changes>
+[user@localhost ~]$ git diff -u > /path/to/nixpkgs/pkgs/applications/science/math/sage/patches/name-of-patch.patch
+```
+
+Now just add the patch to `sage-src.nix` and test your changes. If they fix the problem, [propose them upstream](#proposing-a-sage-patch) and add a link to the trac ticket.
+
+- pin the package version in `default.nix` and add a note that explains why that is necessary.
+
+
+## Proposing a sage patch
+
+You can [login the sage trac using GitHub](https://trac.sagemath.org/login). Your username will then be `gh-<your-github-name>`. The only other way is to request a trac account via email. After that refer to [git the hard way](http://doc.sagemath.org/html/en/developer/manual_git.html#chapter-manual-git) in the sage documentation. The "easy way" requires a non-GitHub account (requested via email) and a special tool. The "hard way" is really not all that hard if you're a bit familiar with git.
+
+Here's the gist, assuming you want to use ssh key authentication. First, [add your public ssh key](https://trac.sagemath.org/prefs/sshkeys). Then:
+
+```
+[user@localhost ~]$ git clone git://github.com/sagemath/sage.git
+[user@localhost ~]$ cd sage
+[user@localhost sage]$ git remote add trac git@trac.sagemath.org:sage.git -t master
+[user@localhost sage]$ git checkout -b u/gh-<your-github-username>/<your-branch-name> develop
+[user@localhost sage]$ <make changes>
+[user@localhost sage]$ git add .
+[user@localhost sage]$ git commit
+[user@localhost sage]$ git show # review your changes
+[user@localhost sage]$ git push --set-upstream trac u/gh-<your-github-username>/<your-branch-name>
+```
+
+You now created a branch on the trac server (you *must* follow the naming scheme as you only have push access to branches with the `u/gh-<your-github-username>/` prefix).
+Now you can [create a new trac ticket](https://trac.sagemath.org/newticket).
+- Write a description of the change
+- set the type and component as appropriate
+- write your real name in the "Authors" field
+- write `u/gh-<your-github-username>/<your-branch-name>` in the "Branch" field
+- click "Create ticket"
+- click "Modify" on the top right of your ticket (for some reason you can only change the ticket status after you have created it)
+- set the ticket status from `new` to `needs_review`
+- click "Save changes"
+
+Refer to sages [Developer's Guide](http://doc.sagemath.org/html/en/developer/index.html) for further details.
+
+## I want to update sage
+
+You'll need to change the `version` field in `sage-src.nix`. Afterwards just try to build and let nix tell you which patches no longer apply (hopefully because they were adopted upstream). Remove those.
+
+Hopefully the build will succeed now. If it doesn't and the problem is obvious, fix it as described in [The sage build is broken](#the-sage-build-is-broken).
+If the problem is not obvious, you can try to first update sage to an intermediate version (remember that you can also set the `version` field to any git revision of sage) and locate the sage commit that introduced the issue. You can even use `git-bisect` for that (it will only be a bit tricky to keep track of which patches to apply). Hopefully after that the issue will be obvious.
+
+## Well, that didn't help!
+
+If you couldn't fix the problem, create a GitHub issue on the nixpkgs repo and ping @timokau (or whoever is listed in the `maintainers` list of the sage package).
+Describe what you did and why it didn't work. Afterwards it would be great if you help the next guy out and improve this documentation!
