.Sh NAME
.Nm finddepends
.Nd find direct dependencies of a package
.Sh SYNOPSIS
.Nm
.Op Fl h
.Op Fl p Ar pkgsrcdir
.Ar pattern
.Sh DESCRIPTION
.Nm
is a perl script for pkgsrc developers that helps finding packages
affected by a recursive PKGREVISION bump.
Given a
.Ar pattern
on the command line, it will recursively find all buildlink3.mk files
that include it, and then find all Makefiles that include any of the
buildlink3.mk files.
.Pp
When reading Makefile.common, it will parse
.Dq # used by
lines and emit those packages too, so there might be duplicates in
the output.
.Pp
.Nm Fl h
displays a short usage.
.Pp
If
.Fl p
is given,
.Ar pkgsrcdir
is used instead of the default
.Pa /usr/pkgsrc .
.Pp
See
.Xr revbump 1
for an example of a complete recursive PKGREVISION bump.
.Sh ENVIRONMENT
.Ev PKGSRCDIR
pkgsrc root directory.
Defaults to
.Pa /usr/pkgsrc .
.Sh EXAMPLES
.Dl finddepends security/libtasn1
.Pp
would first output all buildlink3.mk files that include
security/libtasn1, and then all Makefiles and options.mk files that
include any of the found buildlink3.mk files.
