+# @FUNCTION: hprefixify
+# @USAGE: [ -w <line match> ] [-e <extended regex> ] <list of files>
+# @DESCRIPTION:
+# Tries a set of heuristics to prefixify the given files. Dies if no
+# arguments are given, a file does not exist, or changing a file failed.
+#
+# Additional extended regular expression can be passed by -e or
+# environment variable PREFIX_EXTRA_REGEX. The default heuristics can
+# be constrained to lines that match a sed expression passed by -w or
+# environment variable PREFIX_LINE_MATCH.
+# @EXAMPLE:
+# Only prefixify the 30th line,
+# hprefixify -w 30 configure
+# Only prefixify lines that contain "PATH",
+# hprefixify -w "/PATH/" configure
+# Also delete all the /opt/gnu search paths,
+# hprefixify -e "/\/opt\/gnu/d" configure
