-# Usage: spp [-be] [-Kkey] -Dvar=value ... <in >out
-#
-# Source-file constructs
-#
-# Meaningful only at beginning of line, works with any number of keys:
-#
-# #if[key] Includes text between #if/#end if -Kkey specified,
-# #else[key] otherwise changes text to blank lines; key test
-# #end[key] may be negated by prefixing !, e.g., #if[!key]
-#
-# #begin If -be is specified then lines up to and including
-# #end #begin, and from #end to EOF, are deleted
-#
-# #warn Changed into warning that file is generated
-#
-# // ## Changed into blank line
-#
-# Meaningful anywhere in line, works only for first two keys:
-#
-# {#if[key]?yes} Expands to yes if -Kkey specified
-# {#if[key]?yes:no} Expands to yes if -Kkey, otherwise no
-# {#if[!key]?yes} Expands to yes if -Kother
-# {#if[!key]?yes:no} Expands to yes if -Kother, otherwise no
-# $var$ Expands to value if -Dvar=value given
-#
-# yes, no must not contain whitespace
-#
-# If the environment variable SED is defined, uses that instead of sed
-# If the environment variable NAWK is defined, uses that instead of awk
