I followed this link to install jdk1.7.0. But when I man javac, there is no manpage for that. (Note: Before the installation, man javac gives the manpage for gij.)$ man javacman: can't resolve /usr/share/man/man1/javac.1.gz: No such file or directoryNo manual entry for javacSee 'man 7 undocumented' for help when manual pages are not available.I wonder how can I make man javac and other java related commands work?Here is the man1 dir under the installed dir:$ ls /usr/lib/jvm/jdk1.7.0_67/man/man1/appletviewer.1  jarsigner.1       javah.1     jdb.1    jps.1         jstatd.1        pack200.1      schemagen.1   wsgen.1apt.1           java.1            javap.1     jhat.1   jrunscript.1  jvisualvm.1     policytool.1   serialver.1   wsimport.1extcheck.1      javac.1           javaws.1    jinfo.1  jsadebugd.1   keytool.1       rmic.1         servertool.1  xjc.1idlj.1          javadoc.1         jcmd.1      jmap.1   jstack.1      native2ascii.1  rmid.1         tnameserv.1jar.1           javafxpackager.1  jconsole.1  jmc.1    jstat.1       orbd.1          rmiregistry.1  unpack200.1
