.Sh NAME
.Nm file.personality
.Nd pkgconf cross-compile personality file format
.Sh DESCRIPTION
pkgconf cross-compile personality files provide a useful mechanism for storing
various information about system toolchains.
Information stored by
.Nm .personality
files include information about paths used by a cross-compile toolchain, such as
the sysroot directory and default include and library paths.  pkgconf uses this
information to determine what information is necessary to use libraries.
.\"
.Ss FILE SYNTAX
The
.Nm .personality
file follows a format inspired by RFC822.
Comments are prefixed by a pound sign, hash sign or octothorpe (#), and variable
assignment is similar to POSIX shell.
Properties are defined using RFC822-style stanzas.
.\"
.Ss PROPERTIES
.\"
Properties are set using RFC822-style stanzas which consist of a keyword, followed
by a colon (:) and then the value the property should be set to.
Variable substitution is always performed regardless of property type.
.Pp
There are two types of property:
.\"
.Bl -tag -width indent
.\"
.It Literal
The property will be set to the text of the value.
.\"
.It Fragment List
The property will be set to a list of fragments parsed from the text.
The input text must be in a format that is suitable for passing to a POSIX
shell without any shell expansions after variable substitution has been done.
Elements are delimited with a colon.
.\"
.El
.Ss PROPERTY KEYWORDS
.Bl -tag -width indent
.\"
.It Triplet
The triplet used by the cross-compile toolchain.
(mandatory; literal)
.It SysrootDir
The directory used by the system root of the cross-compile toolchain.
(mandatory; literal)
.It DefaultSearchPaths
A list of directories to look for

files in.
(mandatory; fragment list)
.It SystemIncludePaths
A list of directories that are included by default in the search path for
include files.
(mandatory; fragment list)
.It SystemLibraryPaths
A list of directories that are included by default in the search path for
libraries.
