System managers familiar with the installation of other UNIX programs should beware that IRAF does not always follow to the usual conventions. It is wise to read and adhere to the installation instructions to avoid problems.
# Prepare the root IRAF directory.
if new installation
create iraf account
else if updating an old installation
save locally modified files; delete old system
# Install the files.
login as iraf
unpack the core system distribution
configure the BIN directories
# Merge local revisions into new system.
if updating an old installation
merge locally modified files back into new system
run the iraf install script to complete the installation
checkout the new system
If problems should arise during the installation help is available by posting
a query to one of the adass.iraf newsgroups on USENET, by sending email
to iraf@noao.edu, or via the IRAF HOTLINE (520-318-8160). The IRAF
Web page http://iraf.noao.edu is a good source of information, and
includes access to the
IRAF FAQ list.
