Sparse collection of command line scripts to handle FITS files, in particular X-ray observation files.

• copy_spectra: copy a XSpec-compatible spectrum from one directory to the current, together with response and background files. Let's assume that we have a file called source_sr.pha, containing an X-ray spectrum, two directories above ours, together with its response and background files. The names of these files will be written in the RESPFILE, ANCRFILE and BACKFILE keywords in the header of spectrum file. This scripts reads these keywords and copies the relevant files in the current directory, with a common root name, and changes the relevant keywords in the spectrum file.
