news -- print the revisions summary for the current iraf version
The news task uses the standard IRAF file pager to review a formatted summary of the system revisions for the version of IRAF being run. The revisions summaries for older versions of the system are also provided: use the N and P pager keys to display the next or previous system revisions summary. The revisions summary is given in the file "doc$newsfile".
For reasons of brevity, only the revisions summary is printed. For detailed information on the revisions made to a particular science package, type
cl> help <pkg>.revisions op=sys
where "pkg" is the name of the CL package for which revisions information is desired. For detailed information on the revisions to the system software and programming interfaces, examine the system notes file, given in the file "notes.*" in the directory "iraf$local". The system notes files for older versions of the system will be found in the "doc" directory.
The revisions summary is often lengthy and may be easier to read if a printed copy is made.
Redirecting the output of news , e.g., to lprint , doesn't work at present.
