[Eg1_run] EG1 DST files (important to any current analysis)

[nguler at jlab.org]

Just to remind, One can also use the script located at
/home/nguler/eg1b/inc/runInfo/LIST/LinkDATA.pl
in order to link the dst files with certain selection criteria.
It will create soft links of all files (categorized into our standard beam
energy directories) to a directory of your choice (default is DATA).
Use the script with "LinkDATA.pl -help" option to print its usage.
By using -cache command, it will submit the broken links for recaching.
And each time, it creates the list of broken links under the "report"
directory.. Since running with -cache option takes time, I generally run the
script just to link the data and use the lists created under the report
directory to separately submit the missing files for caching.
