Blame displays the last modification for each line in an RCS file.
It is the RCS equivalent of CVS's "annotate" command.

The rcshist utility displays the complete revision history of a set of
RCS files including log messages and patches. The output is sorted in
reverse date order over all revisions of all files.

Gifsicle manipulates GIF image files on the
command line. It supports merging several GIFs
into a GIF animation; exploding an animation into
its component frames; changing individual frames
in an animation; turning interlacing on and off;
adding transparency; adding delays, disposals, and
looping to animations; adding or removing
comments; optimizing animations for space; and
changing images' colormaps, among other things.

The gifsicle package contains two other programs:
gifview, a lightweight GIF viewer for X, can show
animations as slideshows or in real time, and
gifdiff compares two GIFs for identical visual
appearance.

CDO (Climate Data Operators) is a collection of command line Operators
to manipulate and analyse Climate and NWP model Data.
Supported data formats are GRIB 1/2, netCDF 3/4, SERVICE, EXTRA and IEG.
There are more than 600 operators available.

With CodesUI it is possible to:
- inspect the overall structure of GRIB and BUFR files
- examine the data and metadata of the individual messages
For BUFR data these additional features are also available:
- filtering BUFR messages
- extracting tabular data from BUFR messages
- plotting BUFR observation locations on an interactive map
Please note that although CodesUI has some basic plotting capabilities it is
not a visualisation system.

An application program interface accessible from C and FORTRAN programs
developed for encoding and decoding WMO FM-92 GRIB and WMO FM-94 BUFR messages.
A useful set of command line tools is also provided to give quick access to
GRIB and BUFR messages.

ecCodes is mostly API compatible with its precursor grib_api, with exception
of obsolescent and experimental features, see
https://confluence.ecmwf.int/display/ECC/GRIB-API+migration for details.
This package provides compat symlinks to use as grib_api replacement.

Libaec provides lossless compression of signed or unsigned integers
(samples) of sizes 1 to 32 bits wide. The library achieves best
results for low entropy data as often encountered in space imaging
instrument data or numerical model output from weather or climate
simulations.

Libaec implements Golomb Rice coding as defined in the Space Data
System Standard documents 121.0-B-3 and 120.0-G-2.

Libaec includes a drop-in replacement for the SZIP
library (http://www.hdfgroup.org/doc_resource/SZIP).

Latest generation of the ECMWF's Meteorological plotting software.
It supports the plotting of contours, wind fields, observations,
satellite images, symbols, text, axis and graphs (including boxplots).
Input may be GRIB 1 and 2, NetCDF and BUFR.
Plots can be saved in various formats, such as PostScript, EPS, PDF,
GIF, PNG and SVG.

The netCDF Operators, NCO, are a suite of command line programs known
as operators. The operators facilitate manipulation and analysis of
self-describing data stored in the freely available netCDF and HDF
formats (http://www.unidata.ucar.edu/software/netcdf and
http://www.hdfgroup.org, respectively). Each NCO operator (e.g.,
ncks) takes netCDF or HDF input file(s), performs an operation (e.g.,
averaging, hyperslabbing, or renaming), and outputs a processed netCDF
file. Although most users of netCDF and HDF data are involved in
scientific research, these data formats, and thus NCO, are generic and
are equally useful in fields from agriculture to zoology. The NCO
User's Guide illustrates NCO use with examples from the field of
climate modeling and analysis. The NCO homepage is
http://nco.sourceforge.net/.

A library for manipulating units of physical quantities

plocate is a locate based on posting lists, completely replacing mlocate
with a much faster (and smaller) index. It is suitable as a default locate
on your system.
