    .SH NAME
    pkgconf \- a system for configuring build dependency information
    .SH SYNOPSIS
    .B pkgconf
    [options] [list of modules]
    .SH DESCRIPTION
    .P
    pkgconf is a program which helps to configure compiler and linker flags for
    development frameworks. This allows build systems to detect other dependencies
    and use them with the system toolchain.
    .SH GENERAL OPTIONS
    .TP
    \fB\-\-version\fP
    Display the supported pkg-config version and exit.
    .TP
    \fB\-\-atleast\-pkgconfig\-version=VERSION\fP
    Exit with error if we do not support the requested pkg-config version.
    .TP
    \fB\-\-errors\-to\-stdout\fP
    Print all errors on the main output stream instead of the error output stream.
    .TP
    \fB\-\-silence\-errors\fP
    Do not display any errors at all.
    .TP
    \fB\-\-list\-all\fP
    Walk all directories listed in the \fBPKG_CONFIG_PATH\fP environmental variable
    and display information on packages which have registered information there.
    .TP
    \fB\-\-simulate\fP
    Simulates resolving a dependency graph based on the requested modules on the
    command line. Dumps a series of trees denoting pkgconf's resolver state.
    .TP
    \fB\-\-no\-cache\fP
    Skip caching packages when they are loaded into the internal resolver.  This may
    result in an alternate dependency graph being computed.
    .TP
    \fB\-\-ignore\-conflicts\fP
    Ignore 'Conflicts' rules in modules.
    .TP
    \fB\-\-env\-only\fP
    Learn about pkgconf's configuration strictly from environmental variables.
    .TP
    \fB\-\-maximum\-traverse\-depth=DEPTH\fP
    Impose a limit on the allowed depth in the dependency graph.  For example, a depth
    of 2 will restrict the resolver from acting on child dependencies of modules added to
    the resolver's solution.
    .TP
    \fB\-\-static\fP
    Compute a deeper dependency graph and use compiler/linker flags intended for static
    linking.
    .SH MODULE\-SPECIFIC OPTIONS
    .TP
    \fB\-\-atleast\-version=VERSION\fP
    Exit with error if a module's version is less than the specified version.
    .TP
    \fB\-\-exact\-version=VERSION\fP
    Exit with error if a module's version is not exactly the specified version.
    .TP
    \fB\-\-max\-version=VERSION\fP
    Exit with error if a module's version is greater than the specified version.
    .TP
    \fB\-\-exists\fP
    Exit with a non-zero result if the dependency resolver was able to find all of the
    requested modules.
    .TP
    \fB\-\-uninstalled\fP
    Exit with a non-zero result if the dependency resolver uses an 'uninstalled' module
    as part of it's solution.
    .TP
    \fB\-\-no\-uninstalled\fP
    Forbids the dependency resolver from considering 'uninstalled' modules as part of a
    solution.
    .SH QUERY\-SPECIFIC OPTIONS
    .TP
    \fB\-\-cflags\fP, \fB\-\-cflags\-only\-I\fP, \fB\-\-cflags\-only\-other\fP
    Display either all CFLAGS, only \fB\-I\fP CFLAGS or only CFLAGS that are not \fB-I\fP.
    .TP
    \fB\-\-libs\fP, \fB\-\-libs\-only\-L\fP, \fB\-\-libs\-only\-l\fP, \fB\-\-libs\-only\-other\fP
    Display either all linker flags, only \fB\-L\fP linker flags, only \fB-l\fP linker flags or only linker flags that are not \fB-L\fP or \fB-l\fP.
    .TP
    \fB\-\-keep\-system\-cflags\fP, \fB\-\-keep\-system\-libs\fP
    Keep CFLAGS or linker flag fragments that would be filtered due to being included by default in the compiler.
    .TP
    \fB\-\-define-variable=VARNAME=VALUE\fP
    Define \fBVARNAME\fP as \fBVALUE\fP. Variables are used in query output, and some modules' results may change based on the presence of a variable definition.
    .TP
    \fB\-\-print\-variables\fP
    Print all seen variables for a module to the output channel.
    .TP
    \fB\-\-variable=VARNAME\fP
    Print the value of \fBVARNAME\fP.
    .TP
    \fB\-\-print-requires\fP, \fB\-\-print\-requires\-private\fP
    Print the modules included in either the \fBRequires\fP field or the \fBRequires.private\fP field.
    .TP
    \fB\-\-digraph\fP
    Dump the dependency resolver's solution as a graphviz 'dot' file.  This can be used with graphviz to visualize
    module interdependencies.
    .SH EXAMPLES
    .TP
    Displaying the CFLAGS of a package:
    shell> pkgconf --cflags foo
    .br
    -fPIC -I/usr/include/foo
