[ ^^^^^^^^^ This will be automatically replaced with RCS ID string by SVN
when it is committed to our repository.  If upgrading a port, do not alter
this line back to "$FreeBSD: head/pt_BR.ISO8859-1/books/porters-handbook/book.xml 54410 2020-08-05 22:13:01Z dbaio $".  SVN deals with it automatically.]

[section to describe the port itself and the master site - PORTNAME
 and PORTVERSION or the DISTVERSION* variables are always first,
 followed by CATEGORIES, and then MASTER_SITES, which can be followed
 by MASTER_SITE_SUBDIR.  PKGNAMEPREFIX and PKGNAMESUFFIX, if needed,
 will be after that.  Then comes DISTNAME, EXTRACT_SUFX and/or
 DISTFILES, and then EXTRACT_ONLY, as necessary.]

[do not forget the trailing slash ("/")!
 if not using MASTER_SITE_* macros]

 this may need to be tweaked]
PATCH_DIST_STRIP=	-p1

[maintainer; *mandatory*!  This is the person who is volunteering to
 handle port updates, build breakages, and to whom a users can direct
 questions and bug reports.  To keep the quality of the Ports Collection
 as high as possible, we do not accept new ports that are assigned to
 "ports@FreeBSD.org".]
