rule init ( docbook-xsl-dir ? : docbook-dtd-dir ? ) {
if ! $(docbook-xsl-dir)
{
docbook-xsl-dir = [ modules.peek : DOCBOOK_XSL_DIR ] ;
} if ! $(docbook-dtd-dir)
{
docbook-dtd-dir = [ modules.peek : DOCBOOK_DTD_DIR ] ;
}This would be neater as:
docbook-xsl-dir ?= [ modules.peek : DOCBOOK_XSL_DIR ] ;
docbook-dtd-dir ?= [ modules.peek : DOCBOOK_DTD_DIR ] ;And:
if ! $(.initialized)
{
$(.initialized) = true ;This sets the variable "true" to the value "true" the 2nd time it's called. Probably should be:
.initialized = true ;
