-.SH "NAME"
-flag\-o\-matic.eclass \- manipulate CFLAGS/CXXFLAGS easily and reliably
-.SH "DESCRIPTION"
-The \fBflag\-o\-matic\fR eclass contains a suite of functions to
-manipulate the CFLAGS/CXXFLAGS variables.
-.SH "FUNCTIONS"
-.TP
-.BR "append-flags " "\fI<flags>\fR"
-Add extra \fIflags\fR to the current CFLAGS/CXXFLAGS.
-.TP
-.BR "filter-flags " "\fI<flags>\fR"
-Remove particular \fIflags\fR from CFLAGS/CXXFLAGS. This function
-will only match complete flags.
-.TP
-.BR "replace-flags " "\fI<orig-flag>\fR \fI<new-flag>\fR"
-Replace all occurences of \fIoriginal flag\fR with \fInew flag\fR.
-.TP
-.BR "replace-cpu-flags " "\fI<old cpus>\fR \fI<new cpu>\fR"
-Replace all -march, -mcpu, and -mtune flags which contain \fIold cpus\fR
-with -march, -mcpu, and -mtune flags which contain \fInew cpu\fR.
-.TP
-.BR "get-flag " "\fI<flag>\fR"
-If \fIflag\fR is prefixed with -, then the whole flag will
-be echoed. If just the flag name is specified, and the flag has
-a setting, the value for the flag will be echoed instead.
-
-.I Examples:
-.br
-CFLAGS="-march=i586 -ffast-math"
-.br
-`get-flag -march` == "-march=i586"
-.br
-`get-flag march` == "i586"
-.br
-`get-flag -ffast-math` == "-ffast-math"
-.br
-`get-flag ffast-math` == "-ffast-math"
-.TP
-.BR "is-flag " "\fI<flag>\fR"
-Returns true if \fIflag\fR is in CFLAGS or CXXFLAGS.
-.TP
-.BR "filter-mfpmath " "\fI<math types>\fR"
-Remove specified \fImath types\fR from the selected fpmath units.
-If the user has -mfpmath=sse,386, running `filter-mfpmath sse`
-will leave the user with -mfpmath=386.
-.TP
-.BR "append-ldflags " "\fI<flags>\fR"
-Add extra \fIflags\fR to the current LDFLAGS.
-.TP
-.BR "filter-ldflags " "\fI<flags>\fR"
-Remove particular \fIflags\fR from LDFLAGS. This function
-will only match complete flags.
-.TP
-.BR "filter-lfs-flags"
-Remove flags that enable Large File Support.
-.TP
-.BR "append-lfs-flags"
-Add flags that enable Large File Support.
-.TP
-.BR "strip-flags"
-Strip CFLAGS/CXXFLAGS of everything except for flags known to
-be good flags, or are flags that affect the ABI. Users of stable
-profile are limited to these flags:
-.br
-.I "-O -O1 -O2 -mcpu -march -mtune -fstack-protector -pipe -g"
-.br
-Users of unstable profile are allowed the above flags and these flags:
-.br
-.I "-Os -O3 -freorder-blocks -fprefetch-loop-arrays"
-.TP
-.BR "test_flag " "\fI<flag>\fR"
-Tests to see if \fIflag\fR is supported by the active toolchain.
