9   *  newheader(t,fp)     start new information header identified by string t
10   *  isheadid(s)         returns true if s is a header id line
11   *  headidval(r,s)      copy header identifier value in s to r
12 + *  dateval(t,s)        get capture date value
13 + *  isdate(s)           returns true if s is a date line
14 + *  fputdate(t,fp)      put out the given capture date and time
15 + *  fputnow(fp)         put out the current date and time
16   *  printargs(ac,av,fp) print an argument list to fp, followed by '\n'
17   *  isformat(s)         returns true if s is of the form "FORMAT=*"
18   *  formatval(r,s)      copy the format value in s to r
19   *  fputformat(s,fp)    write "FORMAT=%s" to fp
20   *  getheader(fp,f,p)   read header from fp, calling f(s,p) on each line
21 + *  globmatch(pat, str) check for glob match of str against pat
22   *  checkheader(i,p,o)  check header format from i against p and copy to o
23   *
24   *  To copy header from input to output, use getheader(fin, fputs, fout)
