Summary
@persistent@ is a library for type-safe data serialization. It has many kinds of backends, such as SQL backends (@persistent-mysql@, @persistent-postgresql@, @persistent-sqlite@) and NoSQL backends (@persistent-mongoDB@). While @persistent@ is a nice library for storing and retrieving records, currently it has a poor interface for SQL backends compared to SQL itself. For example, it's extremely hard to do a type-safe @JOIN@ on a many-to-one relation, and simply impossible to do any other kinds of @JOIN@s (including for the very common many-to-many relations). Users have the option of writing raw SQL, but that's error prone and not type-checked. @esqueleto@ is a bare bones, type-safe EDSL for SQL queries that works with unmodified @persistent@ SQL backends. Its language closely resembles SQL, so (a) you don't have to learn new concepts, just new syntax, and (b) it's fairly easy to predict the generated SQL and optimize it for your backend. Most kinds of errors committed when writing SQL are caught as compile-time errors---although it is possible to write type-checked @esqueleto@ queries that fail at runtime. Currently only @SELECT@s are supported. Not all SQL features are available, but most of them can be easily added (especially functions), so please open an issue or send a pull request if you need anything that is not covered by @esqueleto@ on <https://github.com/meteficha/esqueleto/>. The name of this library means \"skeleton\" in Portuguese and contains all three SQL letters in the correct order =). It was inspired by Scala's Squeryl but created from scratch.

General
- doc
- Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
- hscolour
- Include coloured haskell sources to generated documentation (dev-haskell/hscolour)
- profile
- Add support for software performance analysis (will likely vary from ebuild to ebuild)
- test
- Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)

*/*: Inline mirror://hackage and update URIs
This change inlines mirror://hackage in all ebuilds, and updates URIs to the modern form (old URIs redirect to that). The change has been made using the following command: find -name '*.ebuild' -exec sed -r -i \ -e 's@mirror://hackage/@https://hackage.haskell.org/@g' \ -e 's@https://hackage.haskell.org/packages/archive/([^/]*)/([^/]*)/@https://hackage.haskell.org/package/\1-\2/@g' \ -e '/hackage\.haskell\.org/s@\$\{PN}-\$\{PV}@${P}@g' \ -e '/hackage\.haskell\.org/s@\$\{MY_PN}-\$\{PV}@${MY_P}@g' \ -e '/hackage\.haskell\.org/s@\$\{PN}-\$\{MY_PV}@${MY_P}@g' \ {} + Signed-off-by: Michał Górny <mgorny@gentoo.org> - Robin H.

proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
