The code is pretty much straightforward. Here is the explanation:
Code:
awk '
        /TIME:/ {                                       # Search pattern: TIME:
                        T = $0                          # If found assign current record: $0 to variable: T
                        gsub(/[ \t]*TIME: | to/, x, T)  # Substitute 0 or more occurrence of space or tab followed by TIME: with null in variable: T
        }                                               # Also Substitute space followed by to with null in variable: T

        /ax:/ {                                         # Search pattern: ax:
                        AX = $NF                        # If found assign last field: $NF to variable: AX
        }

        /aY:/ {                                         # Search pattern: aY:
                        AY = $NF                        # If found assign last field: $NF to variable: AY
        }

        /aZ:/ {                                         # Search pattern: aZ:
                        AZ = $NF                        # If found assign last field: $NF to variable: AZ
        }

        /^[0-9]/ {                                      # Search pattern: ^[0-9] (record starting with digits)
                        R = $0                          # If found assign current record: $0 to variable: R
                        sub(/\/[ \t]*[0-9]*:/, x, R)    # Substitute 0 or more occurrence of space or tab & by 0 or more occurrence of digits with null
                        print T, AX, AY, AZ, R          # Print values of all variables.
        }

FcPatternBuild(3)														 FcPatternBuild(3)

NAME
FcPatternBuild, FcPatternVaBuild, FcPatternVapBuild - Create patterns from arguments SYNOPSIS
#include <fontconfig.h> FcPattern * FcPatternBuild (FcPattern *pattern, ...); FcPattern * FcPatternVaBuild (FcPattern *pattern, va_list va); void FcPatternVapBuild (FcPattern *result, FcPattern *pattern, va_list va); DESCRIPTION
Builds a pattern using a list of objects, types and values. Each value to be entered in the pattern is specified with three arguments: 1. Object name, a string describing the property to be added. 2. Object type, one of the FcType enumerated values 3. Value, not an FcValue, but the raw type as passed to any of the FcPatternAdd<type> functions. Must match the type of the second argu- ment. The argument list is terminated by a null object name, no object type nor value need be passed for this. The values are added to `pat- tern', if `pattern' is null, a new pattern is created. In either case, the pattern is returned. Example pattern = FcPatternBuild (0, FC_FAMILY, FcTypeString, "Times", (char *) 0); FcPatternVaBuild is used when the arguments are already in the form of a varargs value. FcPatternVapBuild is a macro version of FcPat- ternVaBuild which returns its result directly in the result variable. VERSION
Fontconfig version 2.9.0 16 April 2012 FcPatternBuild(3)
