-=head1 NAME
-
-MDK::Common::System - system-related useful functions
-
-=head1 SYNOPSIS
-
-    use MDK::Common::System qw(:all);
-
-=head1 EXPORTS
-
-=over
-
-=item %compat_arch
-
-architecture compatibility mapping (eg: k6 => i586, k7 => k6 ...)
-
-=item %printable_chars
-
-7 bit ascii characters
-
-=item $sizeof_int
-
-sizeof(int)
-
-=item $bitof_int
-
-$sizeof_int * 8
-
-=item arch()
-
-return the architecture (eg: i686, ppc, ia64, k7...)
-
-=item typeFromMagic(FILENAME, LIST)
-
-find the first corresponding magic in FILENAME. eg of LIST:
-
-    [ 'empty', 0, "\0\0\0\0" ],
-    [ 'grub', 0, "\xEBG", 0x17d, "stage1 \0" ],
-    [ 'lilo', 0x2,  "LILO" ],
-
-where each entry is [ magic_name, offset, string, offset, string, ... ].
-
-=item list_passwd()
-
-return the list of users as given by C<getpwent> (see perlfunc)
-
-=item list_home()
-
-return the list of home (eg: /home/foo, /home/pixel, ...)
-
-=item list_skels()
-
-return the directories where we can find dot files: homes, /root and /etc/skel
-
-=item list_users()
-
-return the list of unprivilegied users (aka those whose uid is greater
-than 500 and who are not "nobody").
-
-=item syscall_(NAME, PARA)
-
-calls the syscall NAME
-
-=item psizeof(STRING)
-
-useful to know the length of a C<pack> format string. 
-
-    psizeof("I I I C C S") = 4 + 4 + 4 + 1 + 1 + 2 = 16
-
-=item availableMemory()
-
-size of swap + memory
-
-=item availableRamMB()
-
-size of RAM as reported by the BIOS (it is a round number that can be
-displayed or given as "mem=128M" to the kernel)
-
-!! "mem=..." is dangerous in 2.4 kernels
-
-=item gettimeofday()
-
-returns the epoch in microseconds
-
-=item unix2dos(STRING)
-
-takes care of CR/LF translation
-
-=item whereis_binary(STRING)
-
-return the first absolute file in $PATH (similar to which(1) and whereis(1))
-
-=item getVarsFromSh(FILENAME)
-
-returns a hash associating shell variables to their value. useful for config
-files such as /etc/sysconfig files
-
-=item setVarsInSh(FILENAME, HASH REF)
-
-write file in shell format association a shell variable + value for each
-key/value
-
-=item setVarsInSh(FILENAME, HASH REF, LIST)
-
-restrict the fields that will be printed to LIST
-
-=item setVarsInShMode(FILENAME, INT, HASH REF, LIST)
-
-like setVarsInSh with INT being the chmod value for the config file
-
-=item addVarsInSh(FILENAME, HASH REF)
-
-like setVarsInSh but keeping the entries in the file
-
-=item addVarsInSh(FILENAME, HASH REF, LIST)
-
-like setVarsInSh but keeping the entries in the file
-
-=item addVarsInShMode(FILENAME, INT, HASH REF, LIST)
-
-like addVarsInShMode but keeping the entries in the file
-
-=item setExportedVarsInCsh(FILENAME, HASH REF, LIST)
-
-same as C<setExportedVarsInSh> for csh format
-
-=item template2file(FILENAME_IN, FILENAME_OUT, HASH)
-
-read in a template file, replace keys @@@key@@@ with value, save it in out
-file
-
-=item template2userfile(PREFIX, FILENAME_IN, FILENAME_OUT, BOOL, HASH)
-
-read in a template file, replace keys @@@key@@@ with value, save it in every homes.
-If BOOL is true, overwrite existing files. FILENAME_OUT must be a relative filename
-
-=item read_gnomekderc(FILENAME, STRING)
-
-reads GNOME-like and KDE-like config files (aka windows-like).
-You must give a category. eg:
-
-    read_gnomekderc("/etc/skels/.kderc", 'KDE')
-
-=item update_gnomekderc(FILENAME, STRING, HASH)
-
-modifies GNOME-like and KDE-like config files (aka windows-like).
-If the category doesn't exist, it creates it. eg:
-
-    update_gnomekderc("/etc/skels/.kderc", 'KDE', 
-		      kfmIconStyle => "Large")
-
-=item fuzzy_pidofs(REGEXP)
-
-return the list of process ids matching the regexp
-

-=head1 OTHER
-
-=over
-
-=item better_arch(ARCH1, ARCH2)
-
-is ARCH1 compatible with ARCH2?
-
-better_arch('i386', 'ia64') and better_arch('ia64', 'i386') are false
-
-better_arch('k7', 'k6') is true and better_arch('k6', 'k7') is false
-
-=item compat_arch(STRING)
-
-test the architecture compatibility. eg: 
-
-compat_arch('i386') is false on a ia64
-
-compat_arch('k6') is true on a k6 and k7 but false on a i386 and i686
