-The Guix daemon allows software builds to be performed under alternate

-purpose.  For instance, you may have a pool of accounts in the
-=guixbuild= group, and then you can instruct =guix-daemon= to use them
-like this:
-
-  $ guix-daemon --build-users-group=guixbuild

-However, unless it is run as root, =guix-daemon= cannot switch users.
-In that case, it falls back to using a setuid-root helper program call
-=nix-setuid-helper=.  That program is not setuid-root by default when
-you install it; instead you should run a command along these lines
-(assuming Guix is installed under /usr/local):

+hierarchical structure to store multiple scalable array-oriented data sets
+with metadata information.  It is suited for large-scale datasets, especially
+for data which are much larger than the available random-access memory.  The
+@code{gdsfmt} package offers efficient operations specifically designed for
+integers of less than 8 bits, since a diploid genotype, like
+@dfn{single-nucleotide polymorphism} (SNP), usually occupies fewer bits than a
+byte.  Data compression and decompression are available with relatively
+efficient random access.  It is also allowed to read a GDS file in parallel

+
+@item Double-ended, thread-safe, growable queues with important points
+in between (such as the queues used for work stealing).
+@end itemize
+
+This package includes an interface for Deques that allows the programmer
+to use a single API for all of the above, while using the type system to
+select an efficient implementation given the requirements (using type families).
+
+This package also includes a simple reference implementation based on

+@item Support for specifying clusters

+@item Generate and parse Dot code with two options: strict and liberal

+
+@itemize
+@item @code{OrdPSQ k p v}, which uses the @code{Ord k} instance to provide
+fast insertion, deletion and lookup.  This implementation is based on Ralf
+Hinze's @uref{http://citeseer.ist.psu.edu/hinze01simple.html, A Simple
+Implementation Technique for Priority Search Queues}.
+
+Hence, it is similar to the @uref{https://hackage.haskell.org/package/PSQueue,
+PSQueue} library, although it is considerably faster and provides a slightly
+different API.
+
+@item @code{IntPSQ p v} is a far more efficient implementation.  It fixes the
+key type to @code{Int} and uses a
+@code{https://en.wikipedia.org/wiki/Radix_tree, radix tree} (like @code{IntMap})
+with an additional min-heap property.
+
+@item @code{HashPSQ k p v} is a fairly straightforward extension
+of @code{IntPSQ}: it simply uses the keys' hashes as indices in the
+@code{IntPSQ}.  If there are any hash collisions, it uses an
+@code{OrdPSQ} to resolve those.  The performance of this implementation
+is comparable to that of @code{IntPSQ}, but it is more widely
+applicable since the keys are not restricted to @code{Int},
+but rather to any @code{Hashable} datatype.
+@end itemize
+
+Each of the three implementations provides the same API, so they can
+be used interchangeably.
+
+Typical applications of Priority Search Queues include:
+

+@item Caches, and more specifically LRU Caches;

+
+To solve those problems this package does the following:
+
+@itemize
+@item Reexport the original APIs under the @code{Rebase} namespace.
+
+@item Export all the possible non-conflicting symbols from the
+@code{Rebase.Prelude} module.
+
+@item Give priority to the modern practices in the conflicting cases.
+@end itemize
+
+The policy behind the package is only to reexport the non-ambiguous and
+non-controversial APIs, which the community has obviously settled on.
+The package is intended to rapidly evolve with the contribution from
+the community, with the missing features being added with pull-requests.")

-
-@itemize
-@item @code{OrdPSQ k p v}, which uses the @code{Ord k} instance to provide
-fast insertion, deletion and lookup.  This implementation is based on Ralf
-Hinze's @uref{http://citeseer.ist.psu.edu/hinze01simple.html, A Simple
-Implementation Technique for Priority Search Queues}.
-
-Hence, it is similar to the @uref{https://hackage.haskell.org/package/PSQueue,
-PSQueue} library, although it is considerably faster and provides a slightly
-different API.
-
-@item @code{IntPSQ p v} is a far more efficient implementation.  It fixes the
-key type to @code{Int} and uses a
-@code{https://en.wikipedia.org/wiki/Radix_tree, radix tree} (like @code{IntMap})
-with an additional min-heap property.
-
-@item @code{HashPSQ k p v} is a fairly straightforward extension
-of @code{IntPSQ}: it simply uses the keys' hashes as indices in the
-@code{IntPSQ}.  If there are any hash collisions, it uses an
-@code{OrdPSQ} to resolve those.  The performance of this implementation
-is comparable to that of @code{IntPSQ}, but it is more widely
-applicable since the keys are not restricted to @code{Int},
-but rather to any @code{Hashable} datatype.
-@end itemize
-
-Each of the three implementations provides the same API, so they can
-be used interchangeably.
-
-Typical applications of Priority Search Queues include:
-

-@item Schedulers;
-@item Pathfinding algorithms, such as Dijkstra's and A*.

-@item Simple, single-ended, non-concurrent, bounded queues
-
-@item Double-ended, thread-safe, growable queues with important points
-in between (such as the queues used for work stealing).

-This package includes an interface for Deques that allows the programmer
-to use a single API for all of the above, while using the type system to
-select an efficient implementation given the requirements (using type families).
-
-This package also includes a simple reference implementation based on

+
+This package provides a static C library of (de)compression functions and some
+simple command-line converters similar to those provided by netpbm.
+
+Two JBIG1 variants are available.  One (@file{jbig.c}) implements nearly all
+options of the standard but has to keep the full uncompressed image in memory.
+The other (@file{jbig85.c}) implements just the ITU-T T.85 profile, with
+memory management optimized for embedded and fax applications.  It buffers
+only a few lines of the uncompressed image in memory and is able to stream

+extension point in a program that allows interleaving the execution of
+arbitrary code with the execution of a the program without introducing any
+coupling between the two.  Hooks are used extensively in the extensible editor
+Emacs.
+
+In the Common LISP Object System (CLOS), a similar kind of extensibility is
+possible using the flexible multi-method dispatch mechanism.  It may even seem
+that the concept of hooks does not provide any benefits over the possibilites
+of CLOS.  However, there are some differences:
+
+@itemize
+
+@item There can be only one method for each combination of specializers and
+qualifiers.  As a result this kind of extension point cannot be used by
+multiple extensions independently.
+@item Removing code previously attached via a @code{:before}, @code{:after} or
+@code{:around} method can be cumbersome.
+@item There could be other or even multiple extension points besides @code{:before}
+and @code{:after} in a single method.
+@item Attaching codes to individual objects using eql specializers can be
+cumbersome.
+@item Introspection of code attached a particular extension point is
+cumbersome since this requires enumerating and inspecting the methods of a
+generic function.
+@end itemize
+
+This library tries to complement some of these weaknesses of method-based
+extension-points via the concept of hooks.")

-Subject: [PATCH] Include <QRegExpValidator> explicitly
-
-Since Qt 5.11, generated ui_getprofilename.h no longer includes QHeaderView
-which breaks the chain that included qvalidator.h in getprofilename.cpp.
-As it feels rather fragile to rely on such indirect includes, let's include
-<QRegExpValidator> explicitly in each file using QRegExpValidator class.

-Subject: [PATCH] xflock4: Do not override PATH with hardcoded value.
-
-The PATH "/bin:/usr/bin" may not be a valid search path on the user's
-machine.  The screen locking program may be in /usr/local/bin or
-elsewhere.  Distros that do not conform to the FHS, such as GuixSD and
-NixOS, will not have their executables in either location.  Thus, we
-simply leave PATH alone.

+differing conventions on the exact appearance of numbers (and units).  A
+number of LaTeX packages have been developed to provide consistent application
+of the various rules.  The @code{siunitx} package takes the best from the
+existing packages, and adds new features and a consistent interface.  A number
+of new ideas have been incorporated, to fill gaps in the existing provision.
+The package also provides backward-compatibility with @code{SIunits},
+@code{sistyle}, @code{unitsdef} and @code{units}.  The aim is to have one
+package to handle all of the possible unit-related needs of LaTeX users.")
