>Description:
	There are some ports where the Makefile contains at least
	one line similar to the following lines:
MAN1 =	something.1
MAN1=     something.1
MAN1= 	something
MAN1=  	something
	Regarding to portlint and porters-handbook, each of those 
	constructs are "wrong" (bacause there are spaces between
	or in front of = and the assignment). Find the script
	which tries to repair this attached.

>How-To-Repeat:
>Fix:


--- clean.sh begins here ---
#!/bin/sh

ERROR() {
	echo $1
	exit $2
}

for file in `find ./ports/ -name Makefile` ; do
	awk '  	{
			a=gensub(/(^[A-Z_+\?0-9]+)[ ]+(=[ \t]+)/,"\\1\\2","g")
		}
		a~/^[A-Z_+\?0-9]+=[ ]+/ {
			gsub(/        /,"\t",a)
		} 
		a~/^[A-Z_+\?0-9]+=[ ]+[\t]+/ || a~/^[A-Z_+\?0-9]+=[\t]+[ ]+/ {
			if(length($1) < 8 ) {
				sub(/[ ]+/,"\t",a)
			} else {
				sub(/[ ]+/,"",a)
			}
		}
		a~/^[A-Z_+\?0-9]+=[ ]+/ {
			sub(/[ ]+/,"\t",a)
		}
		{
			print a
		}' $file > $file.$$ || ERROR "error on processing $file with awk" 1
	mv $file.$$ $file || ERROR "error moving $file.$$ to $file" 2
done
--- clean.sh ends here ---
