Hi all,

Darshan 2.2.0 is now available for download.   This release splits 
Darshan into separate components for instrumentation and analyis.  There 
are also several improvements in documentation, portability, and an 
assortment of bug fixes.

The Darshan web site (http://www.mcs.anl.gov/darshan) also has a new 
documentation section that includes more detailed notes on how to 
install Darshan on various architectures.


* split darshan into separate packages:
   - darshan-runtime: for runtime instrumentation
   - darshan-utils: for processing darshan log files
* changed default output file name for darshan-job-summary.pl to be based on
   input file name rather than summary.pdf
* reorganized init and finalize routines so that can be linked 
separately (to
   allow for easier integration with other instrumentation tools)
* add -cc, -cxx, -f77, -f90, and -fc support to compiler scripts 
generated by
   the darshan-gen-*.pl scripts
* bug fixes:
   - potential MAX_BYTE overflow on 32 bit systems
   - incorrect pread and pwrite offset tracking
   - corrections to darshan-job-summary variance table
   - better runtime error handling if bzip or gnuplot tools are insufficient
   - improvements to time range in darshan-job-summary graphs
* documentation:
   - improved documentation for both the darshan-runtime and darshan-util
   portions of Darshan can be found in the respective doc/ subdirectory for
