Example of a two liner installation:
1% curl ftp://ftp.astro.umd.edu/progs/carma/miriad.tar.gz | tar zxf - or: 1% wget -O - ftp://ftp.astro.umd.edu/progs/carma/miriad.tar.gz | tar zxf - 2% miriad_cvs/install/install.miriad
and a few lines of usage to certify the installation was ok and you probably have a working version:
3% source miriad_cvs/miriad_start.csh 4% imgen out=map0 5% itemize in=map0 6% cgdisp in=map0 device=/xs
Note that this version of MIRIAD is a development version, and contain CVS administrative files to allow you to easily update and get the latest fixes directly via CVS. This is much preferred to downloading a tar file each time and install that.
