  62 =head1 NAME
  63
  64 ff - Find files horizontally, ie. a whole directory level at a time, across subtrees
  65
  66 =head1 SYNOPSIS
  67
  68 ff <B<pattern>> [B<path>-1] [B<path>-2] ... [B<path>-n]
  69
  70 =head1 DESCRIPTION
  71
  72 Search files which name matches to B<pattern> in B<path>s directories recursively, case-insensitively.
  73 The file's path is matched if B<pattern> contains '/'.
  74 Searching is done horizontaly, ie. scan the upper-most directory level first completely,
  75 then dive into the next level and scan those directories before moving to the 3rd level deep, and so on.
  76 This way users usually find what they search for more quickly.
