.Sh NAME
.Nm show-reverse-deps
.Nd show reverse dependencies for a given port
.Sh SYNOPSIS
.Nm show-reverse-deps
.Op Fl ftv
.Op Fl d Ar database
.Ar pkgpath
.Sh DESCRIPTION
.Nm
quickly computes all ports dependent on a given port through a recursive sql
query to
.Pa sqlports .
.Pp
The
.Ar pkgpath
parameter should normally be the fullpkgpath of the port to depend on.
.Pp
Options are as follows:
.Bl -tag -width flagdatabase
.It Fl d Ar database
Choose an sqlite3 database other than the default
.Pa ${TRUEPREFIX}/share/sqlports .
.It Fl f
Fuzzy matching, show dependencies for any path which contains the
.Ar pkgpath
parameter.
.It Fl t
Also include test dependencies.
By default, only other types of dependencies are considered.
.It Fl v
Show verbose results: instead of a list of pkgpath, show every
dependency in the form "fullpkgpath|dependspath|TYPE", where TYPE
is one of 
.Ev LIB_DEPENDS , RUN_DEPENDS , BUILD_DEPENDS , TEST_DEPENDS .
Results can be rather large!
