69     5.4 Configuration Tools in the Project Environment
70     </H1>
71     Although all required external tools are automatically set up by the
72     <SMALL>SCRAM</SMALL>&nbsp;configuration manager in every project area, a developer may
73     want to change settings to suit a local system like a laptop computer.
74     <SMALL>SCRAM</SMALL>&nbsp;provides several commands to allow developers to easily view
75     the configuration environment and also to change it. The list of
76     configured tools available can be obtained using the command
77    
78     <P>
79     <TT>scram tool</TT>
80    
81     <TT>list</TT>
82    
83     <P>
84     This will present a list like the one shown below: <PRE>
85     Tool list for location /home/sashby/work/CMS/Projects/COBRA_6_3_1_pre4
86     ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
87    
88     gcc 2.95.2 (default=2.95.2)
89     g77 0.5.24 (default=0.5.24)
90     qt 3.0.1 (default=3.0.1)
91     clhep 1.7.5.0 (default=1.7.5.0)
92     htl 1.3.2.1 (default=1.3.2.1)
93     hepodbms 0.3.3.1 (default=0.3.3.1)
94     objectivity 6.1.3 (default=6.1.3)
95     heputilities 0.7.0.0 (default=0.7.0.0)
96     lizard 2.2.1.3 (default=2.2.1.3)
97     aida_annotation 2.0.0.0 (default=2.0.0.0)
98     aida_htl 2.0.0.2 (default=2.0.0.2)
99     histoparameters 2.2.0.3 (default=2.2.0.3)
100     </PRE>
101     <P>
102     The settings for a tool can be viewed using the command
103    
104     <P>
105     <TT>scram tool</TT>
106    
107     <TT>info</TT> <TT>tool_name</TT>
108    
109     <P>
110     For example, the settings of the <TT>gcc</TT> compiler would look like
111     this: <PRE>
112     Tool info as configured in location /home/CMS/Projects/COBRA_6_3_1_pre4
113     +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
114    
115     Name : gcc
116     Version : 2.95.2
117     Docfile :
118     cvs://cmscvs.cern.ch/cvs_server/repositories/ToolBox?auth= \
119     pserver&amp;module=ToolBox/CompilerTools/CXX/gcc&amp;passkey=AA_:yZZ3e&amp; \
120     user=anonymous&amp;version=CMS_55_1
121     ++++++++++++++++++++
122     CXX=/usr/local/gcc-alt-2.95.2/bin/c++
123     CC=/usr/local/gcc-alt-2.95.2/bin/gcc
124     CCcompiler=gcc
125     LD_LIBRARY_PATH=/usr/local/gcc-alt-2.95.2/lib
126     </PRE>
127     <P>
128     Another useful command can be used to extract the settings of
129     individual variables for a tool:
130    
131     <P>
132     <TT>scram tool</TT>
133    
134     <TT>tag</TT> <TT>tool_name</TT> [<I>tag_name</I>]
135    
136     <P>
137     where <I>tag_name</I> is the name of a variable relevant for
138     the tool <I>tool_name</I>. If no tag name is given then all
139     variable names will be printed. If this command is used in the
140     following way
141    
142     <P>
143     <TT>scram tool</TT>
144    
145     <TT>tag</TT> <TT>gcc</TT> <TT>LD_LIBRARY_PATH</TT>
146    
147     <P>
148     then <TT>/usr/local/gcc-alt-2.95.2/lib</TT> will be printed. This
149     is especially useful within shell scripts and avoids the need for
150     parsing the command output with shell utilities like <TT>sed</TT> or
151     <TT>awk</TT>.
